Some types of energy: Stored (or potential) energy - Chemically: stick of explosive, coal, rocket fuel - Due to position (e.g. something high can fall) Kinetic energy (moving) Thermal energy (due to heat)

The only way in which the particles can move is to vibrate forwards and backwards. In metals the process is fast, they are good conductors. In non-metals the process is slow. It takes a long time for the particles to pass on their heat. Non-metals are not good conductors. They are good insulators HEAT TRANSFER by CONDUCTION
