How Does Insulation Affect the Rate of Cooling?

... How Does Insulation Affect the Rate of Cooling? P PLANNING The Problem The problem which I intend to investigate is out if insulation affects the rate of cooling, and whether the amounts of insulation would affect the rate of cooling Scientific Background An insulator is any of various substances that blocks or slows down the flow of heat, they can only transfer energy slowly. Many materials make air as an insulator, because air is an excellent insulator. Air can reduce heat lost due to conduction. The material has to trap the air to get the best result. This is to avoid warm air escaping and taking the energy with it. Energy can be transferred in four main ways when you heat something: by conduction, convection, radiation and evaporation. In conduction the particles are joined together by bonds, when the material is heated the particles vibrate really fast, they have kinetic energy. A fairly still part in a cold
