Insulating a copper can Aim The aim of this experiment is to find out which is the best insulator for a copper can filled with hot water. Prediction I predict that the bubble wrap will be the best insulator because it has air bubbles which will stop the heat conducting through the solid part of the bubble wrap because there is a gas (air) which is sealed in a pocket and no heat can be conducted through the solid or convection in the gas because it is sealed in. Fair test I will make this a fair test by; using the same amount of water in each can and starting them at the same temperature. The can will be wrapped once with the insulator, all the lids will be the same, size, thickness and material. Apparatus 4 x copper cans 4 x temperature probes 1 x interface 1 x computer 2 x 250ml measuring cylinders 4 x cardboard lids Sellotape Insulators, Bubble wrap Wool Cotton wool Cardboard Method I will...
