BS (Britsh standard) - Essay Example Managing obsolescence has been proved to be one of the major challenges for a graduate design engineer as obsolescence can adversely affect the life of products in almost all of their stages. The use of commercial parts in systems and the large increase in commercial products have accelerated the rate of obsolescence. As obsolescence is an inevitable part as far as various products are concerned, the only possible solution is to minimize the rate of obsolescence with proper and effective management strategies and planning: â€Å"Obsolescence is inevitable and it cannot be ignored but forethought and careful planning can minimize its impact and its potentially high costs† (British Standard p.1). Obsolescence management thus assumes special significance as it is â€Å"an integral part of design, development, production and in-service support† (British Standard p. 1). The British standard is significant and it is selected for the purpose of study due to its unavoidable imp ortance in effective design management systems. The British standard is relevant and significant to any graduate design engineer because it offers certain clear-cut guidelines â€Å"for establishing a framework for obsolescence management and for planning a cost-effective obsolescence management process that is applicable through all phases of the product life cycle† (British Standard p. 1). The standard is applied to all types of products whether they are electronic, electrical or electro-mechanical components. Thus, for a graduate design engineer a thorough knowledge of the various provisions that can ensure the quality and life cycle costs of various products. The process for selecting the British Standard on obsolescence management include the identification of the potential factors that cause o obsolescence, identification of the possible risks involved in the process, calculation of

Marketing company research - Term Paper Example The sector has been growing at a rapid pace since the last few years, but 2012 was a breakthrough year, as during this period, the industry generated the highest ever revenue. However, the most alarming fact about the consumer electronics market of UAE is that, it is mainly driven by the tourist segment. Hence, the dependency on the tourist segment is extremely high. The local consumers on the other hand are more cautious when it comes to the purchase of electronics product or any other luxury goods. This study will investigate about the possibilities of Sony to gain success in the UAE market. The company is currently dealing with several external business challenges and to curb those issues, they are recommended to launch a new product i.e. a Hi-Fi system with affordable price. The financial crisis of UAE and weaknesses in Dubai is also a cause of concern for the industry. The financial crisis has compelled local consumers to spend in a vigilant way. Despite the stern situation, UAE still remains an attractive market for the companies belonging to the consumer electronics segment. ... (Hsu 223) However, due to stable political scenario there is hardly any external disturbance for the companies operating in this industry. Another beneficial factor is that the people of UK are music-lover and 84% are urbanized population.

Most of the retailers are trying to establish online shopping platforms for the purpose of reducing their cost of operation and distribution. The UAE consumers are demanding products that which has better connectivity, high-end features, and better performance, quality, speed and convenience. The market size of consumer electronics industry of UK is

Which Sources of Knowledge Essay Example for Free

Which Sources of Knowledge Essay Which Sources of Knowledge books, web sites, the media, personal experience, authorities or some other- do you consider most trustworthy, and why? Who Can You Trust? In a world filled with more accessible information than ever before, it is much more difficult to evaluate what is truth and what is not. Which sources can you trust? From books to personal experience, one must look carefully at each and determine its level of reliability. Some of the most trusted sources of knowledge are books. Almost everything we learn in school is from a book. We spend close to $300 every year to buy these teaching tools. Yet, have we ever stopped to think about the credibility of these sources? Many of us read books and automatically assume that the information is true. Our knowledge obtained from books is purely authoritative knowledge (with some exceptions). Therefore, we cannot fully trust the information in a book unless the authorities are credible. How can we establish this credibility? A books credibility relies on its authors credentials, sources, publisher, and copyright date. The author should be qualified in his or her field. One flaw in the book Mere Christianity is the fact that C. S. Lewis is not a qualified theologian, so a reader cannot accept all of his ideas so readily. A reader should always take into account the bibliography to ensure that the author is using factual sources. The book should be published by a well-known company, so that the reader knows the information has been rigorously tested and evaluated. In any book, one should always consider the copyright date. For literature, this will help the reader understand the historical context of the language, ideas, and arguments presented in the story. For science books, the copyright date must be new, because scientific knowledge changes almost every day. More importantly than any of these, it is up to the reader to read critically, being aware of any biases. For example, history books cannot always be trusted because history is often seen through a narrow scope. The American Revolution is so embraced by Americans because the Patriots fought against British oppression and taxes. However, the British taxes were not oppressive at all; they were actually negligible compared to the taxes we pay today. History books bring with them another area of knowledge with its own problems. It is impossible to completely record the events of history with perfect accuracy. Everything written should be read with a critical eye. While much information is obtained through books, surely the largest source of information is the Internet. Can web sites be trusted? Once again, we are faced with the problems of authoritative knowledge with Internet web sites. They are created by someone whom you most likely do not know, so how can you be sure that the information given is truth? Web sites should be treated in the same manner as books, but more web sites should be less trusted than books for several reasons. Almost anybody can create a website, but not everybody can publish a book. A web site does not undergo the same rigorous editing tests that books do. A class of 16 year olds created websites for a school project, but not all of those websites contain truth. When obtaining information from the Internet, it would be even more important to compare the information given from many different web sites. If the same information is found repeatedly and consistently in many different web sites, it is most likely a sure fact. Again, a critical eye must be used, making sure the web site creator bases his or her arguments on logical reasoning and accepted facts, and not careless emotions. Books and web sites are generally trusted sources of knowledge, but the media is a highly criticized medium, for good reason.

Assembling personal computer’s hardware and software

Assembling personal computer’s hardware and software Assembling the Personal Computer Firstly, you will assemble the case. You will need to install the power supply, the motherboard, Graphic card, Microprocessor, Main Memory, Hard disk drive, Network Interface Card and so on are stand offs to hold in the motherboard. You will also need to connect some wires to the motherboard You will need to unwrap the motherboard and microprocessor chip. The chip will have one marked corner that aligns with another marked corner of its socket on the motherboard. Align the corners and drop the microprocessor into the socket. You dont need to apply any pressure if its aligned correctly, it should fall into place. Once you have it in, cinch it down with lever arm Second, you will need to install the heat sink. The CPU box will contain a manual that tells you how to do it. The heat sink will contain either a heat sink sticker or heat sink grease to use when mounting the heat sink on the CPU. To install your heat sink, all you had to do was put it in place, cinch it down with flanges on either side and lock it with a cam. Connect the power lead for the heat sink to the motherboard Once youve chosen the right kind of RAM, its time to install your RAM module into the insides of your desktop. You should handle RAM carefully. The RAM slots are located on the computers motherboard. There are usually two slots, though there may be more. It will probably take more pressure than you would think to get the RAM into place. Each side of the module should also have a rotating arm that will look the RAM down Now your motherboard is ready to put in the case. Your motherboard should have come with a faceplate for its back connectors. You need to put in the plate and press it until it clicks in place. It needs to sit about a quarter of an inch away from the cases surface so that none of its connectors touch the case. Find the screws for set up motherboard in the case. Dont screw them in too tightly .Be very careful when putting in the screws. If you drop them into the case, they could damage the fine wires on the motherboard one goes Installing the hard disk drive and the DVD-ROM drive. The case has a removable bracket with four rubber grommets on it, which line up with four holes on the hard drive. It also came with four screws made just to punch through those grommets. Screw the hard drive into the bracket back into its slot in the case. If you are using IDE/PATA drives, be sure to set the jumpers correctly. Then connect the hard disk to the power using one of the connectors coming off of the power supply. Now install the cables. One side of the cable has a red stripe on it, which makes it pin 1. Look on the motherboard and hook the cable into the IDE connector marked 1. Insert the other end of the cable on the back of the drive. Now the drive is ready to use Now, you will install the CD-ROM drive. Again, set up the jumpers correctly. The CD-ROM drive fits in the front of the case, and you may have to put out a faceplate to make the room for it. Slide it in and screw it into place, making sure that it is aligned with the front of the case. Just as with the hard drive, you can use any available connector from the power supply. You will also use the cable that came with the CD-ROM drive to connect it to the motherboard and plug the other end into the drive. Connect the audio for the CD drive. Next, there is an obvious place for it to plug in on the motherboard and on the drive itself Hard disk devices use a ribbon cable to connect to each other. Ribbon cables have all of the wires laid flat next to each other instead of bunched or wrapped together in a bundle. IDE ribbon cables have either 40 or 80 wires. There is a connector at each end of the cable and another one about two-thirds of the distance from the motherboard connector.. The three connectors are typically different colors and attach to specific items: ï‚ § The blue connector attaches to the motherboard ï‚ § The black connector attaches to the primary (master) drive ï‚ § The grey connector attaches to the secondary (slave) drive. The last step is installing the power supply in the case. The power supply has two sides. The fan side faces outside the case and the wire side face inside. Slide the power supply onto its brackets and secure it with screws. Connect the power connector is leads to the motherboard. These are should be a large one and a small one, and it will be obvious as to where each one goes. You will be left with about 15 more wires. Dont worry the manuals have a page to tell you exactly where each one goes. Each of them has a label that corresponds to a label on the correct port. It is time to turn your machines on and see if its work. If there are a switch on the back of the power supply, make sure it is on. Also make sure that the power supply is set correctly to 110 or 220 volts At the same your personal computer is powering up and already use Installing Net Interface Card 1.

Personal Narrative - A Hole In My Left Shoe :: Personal Narrative Writing

A Hole In My Left Shoe I have a hole in my left shoe. It’s on the inside of my left shoe, and it’s been there since the first week I had these shoes. It doesn’t grow or change, because the circumstances that begot it do not grow or change. It’s there because when I sword fight I drag that foot as part of my footwork. This hole in my shoe is a constant thing in my life. Even when I get a new pair of shoes it will still be back there within a week. Look closely at this hole and you can see into it, into me. You can see a story that begins several years ago. I can see him coming from a distance; we stand in a wide expanse of grassy field in the upper reaches of the North Carolina mountains. The boy is a friend of mine; his name is Lucuse, and I’ve known him for a week and already we have the makings of life long friends. But right now we are enemies of the most mortal kind. We circle each other, a stick in each hand, our sabers, and weapons of choice. We size one another up. He is much bigger than me in all aspects except our height, which I take him by scant inches. I’m faster, and he knows it, but if we should get into a lock and are forced to rely on force he knows he will win. Our plans formulated we begin, a slash, a stab. The world around us blurs; it’s still there, but only as a memory. All that exists is a fog, a fog and my opponent. I see him in his entirety, I see the way his body moves, how each piece of him works to form his bid for my demise. I’m aware of myself; I can sense every movement that wo uld at one time have been taken for granted. Now each step is a chapter in a novel that I can’t put down till the end. The adrenalin pounds in my mind as my opponent strikes at me trying to find a hole in my defense. It is in this feeling that I find true happiness for the first time in my young life. That was then and this is now, and I’m a different person now than I was then.

The boy is a friend of mine; his name is Lucuse, and I’ve known him for a week and already we have the makings of life long friends. But right now we are enemies of the most mortal kind. We circle each other, a stick in each hand, our sabers, and weapons of choice. We size one another up. He is much bigger than me in all aspects except our height, which I take him by scant inches. I’m faster, and he knows it, but if we should get into a lock and are forced to rely on force he knows he will win. Our plans formulated we begin, a slash, a stab. The world around us blurs; it’s still there, but only as a memory. All that exists is a fog, a fog and my opponent. I see him in his entirety, I see the way his body moves, how each piece of him works to form his bid for my demise. I’m aware of myself; I can sense every movement that wo uld at one time have been taken for granted. Now each step is a chapter in a novel that I can’t put down till the end. The adrenalin pounds in my mind as my opponent strikes at me trying to find a hole in my defense. It is in this feeling that I find true happiness for the first time in my young life. That was then and this is now, and I’m a different person now than I was then.

The Influences of C.G. Jung Essay -- Jung

The Influences of C.G. Jung      Ã‚  Ã‚  Ã‚   Carl Gustav Jung was influenced by literature, symbolism, religion, and the occult From a very young age. Jung's influencs remained with him as he became a doctor of medicine and a psychological theorist. The philosophical, the supernatural, the symbolic, the religious, and the occult all influenced Jung's area of psychological expertise, making Jung's psychology not only unique to Jung, but also pioneering in the field of general psychoanalysis.    In Ernest Gallo's article "Synchronicity and the Archetypes. (Carl Jung's Doctrines)", Gallo cites that Jung was "deeply drawn to the occult" (Gallo, 1994). Jung's younger cousin, Helen Preiswerk, had the ability to actually shatter knives in a drawer "with a loud bang" (Gallo, 1994). This and other similar cases caused Jung to write his medical dissertation about occult phenomena using this cousin as his subject. Gallo continues by citing that "while Jung was arguing with Freud about psychic phenomena, a loud noise emanated from a bookcase; Jung predicted that it would be repeated and was highly impressed when this portentous prediction came true." (Gallo, 1994). Jung also reported that "he saw the vision of a face half buried in the pillow next to him" (Gallo, 1994). Despite Jung's lack of doubt toward these experiences, Gallo says that "Jung was far more than a simple occultist." (Gallo, 1994), and that Jung was "engagingly skeptical about his wilder speculations" (Gallo, 1994).    The son of a Protestant Minister, Jung also had ties to western religion.

Research question †How many molecules are there in a liquid drop? Essay

Variables – Independent variable – The nature of the liquid drop. Dependent variable – Mass of liquid drop. Constants – * Concentration of the liquids * The volume of a drop * Temperature of the liquids Hypotheses and prediction – The heavier the liquid used i.e. a liquid with a high relative molar mass, the more the number of molecules per drop. I predict this as the RMM (relative molar mass) is the measure of the mass of molecules that make up a mole of a substance, and hence the higher the mass is, the more the number of molecules there have to be. Thus, the liquid would have more number of molecules per unit volume as compared to one with a lower RMM, keeping in mind the same concentration is taken. Apparatus – 1. Measuring scale, in grams (à ¯Ã‚ ¿Ã‚ ½ 0.01 g) 2. Dropper 3. Beaker, 50 ml 4. Distilled water 5. Glycerine 6. Ethanol 7. Ethylene glycol 8. Tissue paper Methodology – 1. We collected the apparatus needed and measured the mass of the 50 ml beaker. We called it m1. 2. Using a dropper, we put 20 drops of water in the beaker. We measured the mass of the beaker + water, and called it m2. The mass of the 20 drops of water was found by subtracting m1 from m2. The answer was divided by 20 to find out the mass of one drop of water. 3. We repeated step 2, with water, using 40, 60, 80 and 100 drops. This made the experiment more accurate i.e. gave a more precise mass of the water drop. 4. then, we repeated steps 3 and 4 with the three other liquids – ethanol, glycerine and ethylene glycol. 5. Values were noted down. Further calculations were made using the mole equation – Number of moles = And, also using Avogadro’s constant, where the number of molecules in one mole of a substance is 6.023 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½. Controlling, varying and monitoring the variables – > The independent variable was varied by using not one, but four different types of liquid. These were – distilled water, glycerine, ethanol and ethylene glycol. These liquids have different relative molecular masses. > The change of the dependent variable were monitored by using a measuring scale to observe the change in the masses of the same number of drops when different liquids were tried. > The controlled variables were kept constant:- (a) All the four liquids had the same concentration of 1 mol/dmà ¯Ã‚ ¿Ã‚ ½. This was necessary as a change in the concentration produces a change in the number of moles of the liquid in the drop. (b) The drops were all of the same sizes, and hence of the same volume. the volume was kept constant by using the same dropper for each trial, and furthermore, by applying the same pressure (from the fingers) to the bulb of the dropper. (c) The temperature of the liquid was necessary to keep constant as even trivial changes in temperatures can make a liquid expand or contract, changing its volume. The experiment was carried out at room temperature, for all trials. The temperature of the surroundings was unchanged throughout the experiment i.e. the temperature of the air conditioner was not altered. Collecting relevant and sufficient data – Before the experiment, several trials were executed in order to get a gist of the experiment and recognize and amend any errors. Examples of errors include applying different amounts of pressure on the dropper bulb, giving us drops of different volumes. We also noticed that sometimes, more or less drops were added than needed, due to not observing well or counting the number of drops being put into the beaker carefully. We corrected this by paying more attention to the number of drops being put into the beaker. These errors were made right and taking trials before the experiment ensured we had a more precise, accurate and relevant experiment. We also decided to take the mass as the dependent variable, instead of volume, as we were provided with a measuring scale which was much more accurate (à ¯Ã‚ ¿Ã‚ ½ 0.01 g) as compared to even the most accurate measuring cylinder (10 ml, à ¯Ã‚ ¿Ã‚ ½ 0.1 ml). This reduced the overall uncertainty of the equipment used and hence the general error of the experiment, and made the data more relevant and certain. On the other hand, it was made sure sufficient data was collected as we took five different trials (20, 40, 60, 80 and 100 drops) for each of the four liquids, just to average it down and get the mass of one drop (for each liquid). Furthermore, we measured the masses of high numbers of drops ex:- 60, 80, 100 drops etc. as the higher the number of drops, the lesser the error uncertainty. The standard deviations of the averages of each set of drops has not been calculated, as it isn’t the final value needed (i.e. the average mass of one drop is the final value needed). I have rounded off those averages to three decimal places (instead of one) as the values are very small. The average mass of one drop has been rounded off to the same number of places as the standard deviation, that is two significant figures. The calculations are shown on the following page. Calculations – * The averages have been calculated the following way:- For example, taking the values for water = = = = 0.0634 = 6.3 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½ (to one dp) * The standard deviation for the averages have been found out in the following way:- 1. First the average of the values have been found. Taking the example of the values of water the average is 6.3 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½ g (0.0634 g). 2. Then, the difference between each reading and the average was found. That is: 0.058 – 0.0634 = -0.0054 0.059 – 0.0634 = -0.0044 0.065 – 0.0634 = 0.0016 0.067 – 0.0634 = 0.0036 0.068 – 0.0634 = 0.0046 3. Next, these differences were squared (in order to remove any negative signs): (-0.0054)à ¯Ã‚ ¿Ã‚ ½ = 2.916 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½5 (-0.0044)à ¯Ã‚ ¿Ã‚ ½ = 1.936 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½5 (0.0016)à ¯Ã‚ ¿Ã‚ ½ = 2.56 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½6 (0.0036)à ¯Ã‚ ¿Ã‚ ½ = 1.296 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½5 (0.0046)à ¯Ã‚ ¿Ã‚ ½ = 2.116 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½5 4. These squares were then added, and the sum was divided by (n – 1), where â€Å"n† is the number of values. = 2.13 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½5 5. Finally, the square root of this number gives the standard deviation of the average: = à ¯Ã‚ ¿Ã‚ ½ 4.615 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½ However, this value is always rounded off to one significant figure (hence, so is the average value) giving – à ¯Ã‚ ¿Ã‚ ½ 0.2 s. 6. This method was used to get the standard deviation of the rest of the four averages as well. * The number of moles of the liquid contained in the drop was calculated by the formula = Number of moles = . The relative molar masses of the four liquids were taken from literature values – Water – 18 ; Glycerine – 92 ; Ethanol – 46 and Ethylene Glycol – 62. (www.wikipedia.com) * The number of molecules present in the drop was found out by using Avogadro’s formula which states – Number of molecules = Number of moles of the substance à ¯Ã‚ ¿Ã‚ ½ (6.023 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½) Data processing – Graph 1 – This graph shows us two things – the mass of the liquid drop as well as the number of molecules each drop contains – of four different liquids, which are placed on the X axis. Comparing this graph, and literature values, we can see there is an indirect relationship between the mass of the drop and the number of molecules. This relationship is most importantly affected by the relative molar mass (RMM) of the liquid. A higher RMM means a lesser number of moles in a given volume, as is seen in the case of glycerine, where the number of molecules is seen to be relatively lesser when compared to its mass; and other values. This means that glycerine’s molecules are heavy, large or more dense. Whereas in the case of water, the number of molecules is seen to be much higher as compared its mass – which suggests that water has a lower RMM, relatively, and hence is â€Å"lighter†, or smaller, on the whole. This graph also shows us anomalous results regarding the mass of the ethylene glycol drop. Technically, the ethylene glycol drop should have a greater mass as when compared to ethanol, as it has a greater RMM (value got from literature data) and a lesser number of molecules. This could have been due to errors in the volume of the liquid drop (for example), which have been explained in the evaluation. Conclusion – Thus, we can conclude by stating that the hypothesis has been proved wrong i.e. as the relative molecular mass of a liquid increases, or the mass of the liquid drop increases, the number of molecules it contains decreases. This is because the relative molar mass is a measure of the mass of one mole of a substance (relative to 1/12 of the mass of carbon 12), and one mole of any substance consists of the same number of molecules – 6.023 à ¯Ã‚ ¿Ã‚ ½ 10à ¯Ã‚ ¿Ã‚ ½Ãƒ ¯Ã‚ ¿Ã‚ ½. However, one mole of a substance may differ in mass from one mole of another substance. This is solely because of the mass of the particles contained in that one mole of the substance. A compound which has i) many atoms ii) heavy atoms (in one molecule), will have a higher relative molar mass than a molecule of a compound which has lesser atoms or lighter ones (or both). In this experiment, we are not measuring the number of molecules in one mole of these for substances, but in one drop. hence, the volume remains constant here. Thus, the only way a drop of a substance (of the same volume as the other three drops) will have more number of molecules than any other will be by the liquid having a lower RMM, so that more number of particles would fit in that drop. Taking the example of water, its mass is relatively lower as compared to the number of molecules it contains. This simply suggests that a water molecule will either have lesser atoms, or lighter atoms, or both. On the other hand, the molecule of glycerine is fairly heavy, with an RMM of 92 (whereas the RMM of water is 18) and we can see by the graph that the number of molecules it has is relatively lower than that of water’s however the mass of the drop is higher than that of water’s. This shows that glycerine molecules are heavier than water molecules. Thus, as the mass of the drop increases, the number of molecules it contains decreases. Errors and observations – > Glycerine doesn’t dissolve in water, hence it was difficult to clean the dropper and the measuring cylinder containing it. > Ethanol, being an alcohol, was volatile. Thus, it easily evaporated. This could have been the reason why the mass of the ethanol drop was lower than expected. > Any slight changes in the room temperature would have caused an error to the volume of the drop, since it is so small in volume, ex:- opening of the laboratory door, changing of the temperature of the air conditioner, opening of the windows. However, it was made sure as far as it could to avoid these changes. > The same dropper was used for each liquid, in order to try to maintain the volume of the drops. This could have resulted in the liquids mixing up, hence altering the mass values. > Minute air particles like dust and dirt could have affected the experiment by changing the mass of the drops. > The readings taken towards the end of the laboratory session were slightly heavier (due to some liquid still remaining in the instrument). > The angle with which the dropper was held made a difference to the size of the drop i.e. if the drop was held vertically, the drops flowed faster and were heavier. Whereas if the dropper was held more horizontally, the speed of the flow of the drops was slower and the size was smaller. > After filling the dropper, the first drops were slightly heavier as compared to the last ones due to the extra pressure being applied to them from the liquid above. > Air bubbles were trapped in the liquids. > Glycerine had the largest and most viscous drops whereas water had the smallest and least viscous drops. > Sometimes, drops were added to a measuring cylinder which already contained drops, intentionally. For example, if a measuring cylinder had 20 drops of water, 20 more drops were added and then the mass for 40 drops of water was measured. In case there were any errors for the first 20 drops, they could have carried on for the next 20 drops. > The liquids could have been slightly impure, as they were all being used for the same experiment (some could have mixed). This would have made a difference to the mass. Evaluation – 1. In order to clean the glycerine left from the sides of the dropper etc, a substance which dissolves glycerine could have been used, for example alcohol. 2. Since ethanol was volatile, the experiment could have been carried out in an area where there was no straight wind. The ethanol bottle could have been kept shut for most of the time, and the masses could have been taken down quickly. 3. The room temperature could have been well monitored by maintaining a constant temperature (of the air conditioner) and strictly ensuring that the windows or the door weren’t opened. 4. Extra care and hygiene could be taken to ensure that the liquids didn’t mix up. This could be done by making sure that attention is paid to the lab while performing it and the volunteers aren’t distracted. To make sure the dropper was well cleaned for each trial, liquids which dissolved the liquids being used could have been applied. Another way could be to find another dropper with the exactly same diameter as the one being used. This would decrease the errors by a great deal. 5. To ensure dust particles didn’t fall into the liquids, a conical flask could be used. 6. After each trial, it should be made sure that the beaker is cleaned well and wiped well too, by tissue paper. In order to ensure that there is no extra liquid remaining, the mass of the beaker could be checked before adding the drops. 7. One set angle (of the dropper) should be used, for example the dropper could held at approximately 45à ¯Ã‚ ¿Ã‚ ½ to the laboratory surface table for all trials. The pressure applied to the bulb should also be monitored. 8. When the dropper is full, the experiment could be carried out more slowly and the number of drops be carefully monitored. This would make sure that the size of the drops was not too large, and that the number of drops being added to the beaker were carefully monitored. 9. To decrease the number of air bubbles, the bottles which contained the four liquids could be shut for most of the time and not moved around much. It should also be made sure that the dropper was full with sufficient liquid so that there would be very less air bubbles, or none at all. 10. To avoid carry-on errors, each trial could be performed after cleaning the beaker with water and wiping it well with tissue, each time. These would be the improvements I would add to my experiment in case I perform it again. I would also like to use more, different liquids, in order to get a broader idea of the experiment.
