HEAT TRANSFER THROUGH CONVECTION. Like conduction and unlike radiation, convection requires a medium. However, in conduction the heat is transferred from one molecule to another, whereas in convection the heated fluid itself is actually moving. As it does, it removes or displaces cold air in its path.
The transfer of heat energy through liquids and gases by the movement of molecules. When molecules of the liquid or gas come in contact with a source of heat, they move apart and away from the source of heat, and cooler molecules take their place.
