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.
An example is when a spoon heats up in a hot pot of soup. The transfer of heat by the movement of a heated fluid is called convection. Fluids include liquids and gases. flow, transferring heat energy from one part of the fluid to another. movement of the fluids within a lava lamp is an example of convection.
