The materials I will use are; wool, cotton wool, cotton, felt, foam, polystyrene and newspaper. As it is difficult to accurately measure which materials stop heat loss from the body, I will instead measure heat loss from a conical flask. I will be testing which material insulates the best, and I will keep all the other variables constant. As 36.9°C is quite a low temperature I will use a higher one, 80°C, to test each material. The amount of water, as well as the starting temperature will be kept constant throughout; as will the size and shape of the conical flask. There will be a beaker around the conical flask, holding the insulator, so this test is on a constant volume, rather than mass of insulator. There will also be another...
