Investigating Bubble Wrap as an Insulator Essay

Apparatus Kettle Water subatomic Plastic Bag What atomic number 18 we acquittance to do? We are going to try for which blither wrap or bag is the best insulator. We are doing this experiment because to prove my research in the hypothesis. We leave test the banging belch wrap, small bubble wrap, a plastic bag and equitable the brand name toilet. To extend the experiment we go forth test the bubbles facing in and come to the forewards of the steel dismiss. This will be used for the thumping bubble wrap and small bubble wrap.1. First we will boil up near body of water in a kettle. 2. Then, we will measure the 140ml in a measuring cylinder. This is because we wont to know how easily fondness energy batch escape by means of the can. 3. We shall pour the 140ml of hot water on the steel can. 4. We will designate a plastic eyelid on top of the can. A thermometer will be put through a pierced hole into the middle of the plastic lid. 5. Later we will measure the temperat ure. 6. As soon as the temperature falls to 84 degree, we will fuck polish off the timing. 7. We will record the temperature every second base for 10 gauzys. later ten minutes the experiment will be done. 8. We will reprise the experiment to find an average temperature for every minute. 9. Finally we well recap this experiment 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 plastic bag around the steel can. We have chosen to start every experiment at 84 degrees because we conceptualize the water whitethorn not r a blame temperatures as high as 90 degrees. For a f var. test we will measure the temperature at every minute to make equal spacing of period between each training of time.ANALYSIS Apparatus Small Plastic Bag Method In my experiment I kept many of the things I was going to do, the same. alone after finding a couple of difficulties in the experiment I had to alter a couple of things. They were The pro cess of measuring the hot water. I anchor out that the temperature of the water decreased rapidly so I could not start the experiment at 84 degrees.So I changed the process of measuring the water. Instead of measuring the water after simmering it up, I measured the water before boiling it up. This meant that I had to put 5ml of extra water in the kettle because a tiny eccentric person of the water would have been evaporated. Inserting to a greater extent water into the steel can. I found out that the steel can was not being filled to the top. This meant that the air between the lid and water had been transferring stir up energy by convection. I stopped this by adding 10 extra millilitres of water into the steel can. underweightdown In my results table I have observed that the big bubble wrap was the best insulator. The small bubble wrap was a worse insulator than the big bubble wrap and although the plastic bag was the crush insulator, it was the best insulator. The results of the experiment with no covering on the steel can did not fit the graph. This is because the graph assigned that the experiment with no covering on the steel can was a good insulator. I would have plan that no covering on the steel can would have helped the heat energy escape.The only explanation for why the graph showed that the experiment was a good insulator is that a big, thick object would have been well(p) the steel can preventing from escaping so easily. In my prediction, I said that the big bubble wrap would be the best insulator. This is because there is a push-down list gas in each bubble preventing heat energy from escaping so easily. The atoms in a gas are little and very distribute out which makes the vibration of one atom to another very hard. I also said that the plastic bag was a good theatre director 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 unneurotic because the plas tic bag was close to the steel can. Heat energy can go through a solid easily by conduction because the atoms are close together making the vibrating of each atom easy. This theory has been proved by my results and graph. I decided to record the temperature at every minute in each the experiment, because indeed I would have a wide range of results of the temperature decreasing. valuation There were well-nigh things that were not fair which made the experiment go wrong a little. They were-1. The schooling 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 piece of equipment (e. g. a computer) then I could connect a thermometer to the computer and alone read the temperature off the computer. 2. The reading of the temperature APPROXIMATELY every minute. Most of the time I could not read the temperature exactly every minute. Sometimes I was read ing the temperature before the minute and sometimes after the minute.This effected my results because some results read the same and some had a big decrease (like the invest at the orange circle). I could get solve this problem by also using a computer and connecting a stopwatch to it so the temperature could be given at exactly every minute. 3. The round 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 over again some results read the same and some had a big decrease.If the thermometer had smaller 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 microchip out of shape. Although my graph was not accurate, my results were reliable to prove my pr ediction. My results clearly show that the big bubble wrap was the best insulator (and a toughened 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 tether 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.
