Does 80 Degree Celsius Water Reduce In Temperature
Introduction
In this experiment, we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes, using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil, plastic wrap, newspaper, felt, and bubble wrap.
Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss, but Aluminium foil is also useful for protecting objects from gaining unwanted heat.
Plastic wrap insulates the heat but makes it that it is too hot to touch. Plastic wrap is reflective which should make it a good insulator, however the plastic is too thin and lets heat escape. the reason …show more content…
The results did not support my hypothesis( which was the aluminium foil will insulate the heat the best) because the felt was made of cotton which is a material that is used for making clothing that should insulate heat. The gladwrap however let steam escape and was letting the heat leave from the conical flask. The explanation of this unexpected result is that felt has air pockets in them which hides the heat but at the same time helps keeps the water at its hottest temperature it can be, because it is surrounded in heat. The experiment was a fair test except for the newspaper, because when the material was getting tested time ran out so in the next lab lesson that was done it was started at the time we left the newspaper at, instead of doing the test from the very beginning. To make sure that the other materials that we tested was a fair test is that we cooled down the conical flask before moving on to the next material and making sure that the conical flasks were all at the same time in the beginning. There was no sources of error except for the part of the newspaper, and to improve our experiment we should be focused on the time and not recording temperatures and observations a bit late. To take this investigation further we use the felt which was the best insulator and test it on other liquids to see if the results would be any different, and if they are, what is affecting the
