Testing insulators Aim: My aim is to investigate and record the change in temperature when I change the insulator on a copper can for the duration of 10 minutes at one minute intervals. I will be investigating which insulator is best this will be decided by which insulator has the highest temperature at the end of the experiment. Conduction Heat energy can be transferred from one substance to another when they are in direct contact. The moving molecules of one material can increase the energy of the molecules of the other. The heat can also travel through a material as one molecule transfers energy to another one. This type of heat transfer is called conduction. Conduction is mainly seen with solid objects, but it can happen when any materials come into contact, like when warm air is in contact with your skin. Some materials are better conductors of heat than others. For example, metals are...
