... Science Heat Loss Investigation Da don Ranjit dhillon'z coursework, Introduction In this investigation I will investigate heat loss and heat transfer in different materials and I will also investigate which materials are the best insulators. A material that prevents this heat loss is called an insulator and this helps to keep the object that is being insulated warmer for, longer. Heat is generally transferred in three different methods: - - Conduction - Convection - Radiation Conduction is energy transferred from the hotter part of a solid to the colder part of conduction. It is transferred by the particles in the material the particles in the hot part are vibrating more. These vibrations are passed on to the cooler particles next to them, so the energy spreads through the material until all particles have the same energy. Metals are good conductors, whereas most non-metals are poor conductors and poor conductors are used as insulators. Convection is the
