HEAT TRANSFER MECHANISMS Heat energy is being transferred from one location to another because of a temperature difference. The three mechanisms for heat transfer are: • Conduction. When you grip the hot handle of a pan on a stove‚ you feel conduction in action. Heat flows from the pan and along the length of the handle to its cooler free end.
