The reliability of the people giving you the facts is as important as the facts themselves.
Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of unknown conduction and advection.
There are basically three methods of heat transfer; what causes the heat transfer differs in each of the three methods. Conduction: Atoms/molecules simply bump into one anothe â¦ r, transferring energy. Convection: Larger amounts of liquids or gases move up if they are hotter, because they are less dense.
