An Article on How Heat is Transferred
Conduction is the transfer of heat between substances that are in direct contact with each other. Metal is a good conduction of heat. Conduction occurs when a substance is heated.
Heat energy is transferred from hot places to cold places by convection. Convection happens when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This result is ongoing circulation.
