WebHeat energy can move from hot objects, liquids, gases, or spaces to cooler ones through three methods of transfer: conduction, convection, and radiation. Conduction is when heat passes through solid material to increase the temperature of whatever is beyond it. WebIt is the movement of huge amounts of material, taking the heat from one area and placing it in another. Warm air rises and cold air replaces it. The heat has moved. It is the transfer of heat by motion of objects. Convection occurs when an area of hot water rises to the top of a pot and gives off energy.
