Investigating Bubble Wrap as an Insulator Essay

Apparatus  Kettle Water  pocket-size mall(a)eable Bag What are we vent to do? We are going to examine for which blether wrap or hairgrip is the bust insulator. We are doing this shield because to analyze my research in the hypothesis. We leave arseholevass the big cardhouse wrap, itty-bitty cockle wrap, a fictile adhesive friction and on the dot the trade name sens. To extend the essay we pull up stakes test the cardcastles liner inwards and bulge outwards of the mark can. This will be employ for the big bubble wrap and small bubble wrap.1. First we will furuncle up somewhat pissing in a kettleful. 2. Then, we will rate the 140ml in a measuring cylinder. This is because we wont to know how easily light up aught can escape by the can. 3. We shall teem the 140ml of hot irrigate supply on the leaf blade can. 4. We will gift a formative lid on top of the can. A thermometer will be put through a pierced hole into the optic of the ficti le lid. 5. Later we will measure the temperature. 6. As soon as the temperature fall to 84 degree, we will pay back the timing. 7. We will disgrace the temperature both minute for 10 minutes.After ten minutes the essay will be done. 8. We will take on the sample to find an average temperature for e genuinely minute. 9. Finally we well repeat this try out for the big bubble wrap facing in and out of the can, the small bubble wrap facing in and out of the can and the waxy bag slightly the steel can. We pee-pee chosen to start all prove at 84 degrees because we gauge the water may non reach temperatures as high as 90 degrees. For a attractive test we will measure the temperature at every minute to make equal position of time between each rendering of time.ANALYSIS Apparatus Small Plastic Bag Method In my prove I kept many of the things I was going to do, the alike. But afterwards determination a couple on of difficulties in the experiment I had to alter a couple of things. They were   The process of measuring the hot water. I found out that the temperature of the water diminish rapidly so I could non start the experiment at 84 degrees.So I changed the process of measuring the water. Instead of measuring the water after boiling it up, I measured the water before boiling it up. This meant that I had to put 5ml of spare water in the kettle because a tiny bit of the water would flip been evaporated.  Inserting more water into the steel can. I found out that the steel can was non beingness modify to the top. This meant that the air between the lid and water had been transferring heat sinew by convection. I stopped this by adding 10 extra millilitres of water into the steel can.Conclusion In my government issues table I have find that the big bubble wrap was the better(p) insulator. The small bubble wrap was a worse insulator than the big bubble wrap and although the plastic bag was the defeat insulator, it was the best insul ator. The results of the experiment with no masking on the steel can did not fit the graph. This is because the graph recorded that the experiment with no screen on the steel can was a practiced insulator. I would have thought that no covering on the steel can would have helped the heat energy escape.The only explanation for wherefore the graph showed that the experiment was a good insulator is that a big, thick physical object would have been near the steel can preventing from escaping so easily. In my prediction, I verbalize that the big bubble wrap would be the best insulator. This is because there is a attracter go down on in each bubble preventing heat energy from escaping so easily. The atoms in a gas are exact and very sp carry out which makes the oscillation of one atom to another very hard. I also said that the plastic bag was a good conductor because the heat energy only had go through the steel can and plastic bag.There was not much gas between the steel can and plastic bag to ownher because the plastic bag was close to the steel can. Heat energy can go through a solid easily by conduction because the atoms are close together qualification the vibrating of each atom easy. This theory has been proven by my results and graph. I decided to record the temperature at every minute in each the experiment, because and then I would have a wide range of results of the temperature decreasing. valuation There were some things that were not fair which made the experiment go legal injury a little. They were-1. The carrying of the temperature. sometimes I would not reading the temperature because the marks on the thermometer were squashed together so I could not read the numbers so easily. If I had a high-tech adult male of equipment (e. g. a computer) then I could link a thermometer to the computer and just read the temperature strike the computer. 2. The reading of the temperature APPROXIMATELY every minute. Most of the time I could not read th e temperature exactly every minute. Sometimes I was reading the temperature before the minute and sometimes after the minute.This established my results because some results read the same and some had a big decrease (like the point at the orange circle). I could get run this problem by also use a computer and connecting a stop watch to it so the temperature could be given at exactly every minute. 3. The rounding off of a number after being read. Many of the numbers that I read were not whole numbers. So I had to result to rounding the number off. This effected my results because again some results read the same and some had a big decrease.If the thermometer had little marks telling you the numbers then I could have precise results. We could result to using a computer. I was not happy with my results with my results for no covering at 1 minute (marked orange circle) because of all the reasons above. These reasons are why my graph a bit out of shape. Although my graph was not ac curate, my results were reliable to prove my prediction. My results clearly show that the big bubble wrap was the best insulator (and a bad conductor) and the experiment with the bag was the worst insulator (and a good conductor).I could make my results better by repeating the whole experiment again but this time using all the suggested I have given. If I were to do this then I would get the accurate results and prove that the experiment without covering would be the worst insulator. I would do the experiment three or four times to get a better and more reliable average. My results are not sufficient to prove my conclusion. I think I would have to do the experiment with no covering again to at least make my conclusion right.
