The effect of insulating materials on heat loss from the body Richard Smith 5? Introduction In this experiment I will be testing six different materials, felt, cotton wool, bubble wrap, polystyrene, wool and cotton. The other variables, for example, the number of layers, the amount of water in the flask, and the size of the flask, will be fixed to enable a fair test. I will use 200 cm3 of water in the flask, which will be inside a beaker full of the insulating material. Prediction I think that the polystyrene will be the best insulator, because after looking at all the materials under a microscope, I found that polystyrene had the smallest air spaces. This means that the air in those spaces will take the least time to heat up and therefore less heat is lost in the heating. I think that the bubble wrap will be the worst insulator, because it...
