The transfer of heat by the movement of a heated fluid is called convection. Fluids include liquids and gases. During convection, heated particles of a fluid begin to. flow, transferring heat energy from one part of the fluid to another.
Convection The method of heat transfer called convection occurs in fluidsâthat is, liquids and gases. It is usually a fairly rapid process. It depends upon the movement of the material that is heated. The motion is a result of changes in density (mass per unit volume) that accompany the heating process. Water in a teakettle is heated by convection.
