Answer:
True
Step-by-step explanation:
Convection simply means the transfer of heat resulting from the movement of the molecules of fluid, which can be liquid or gas.
Convection can either be natural or forced. natural convection occurs by a natural means ,such as the difference in density of warm air and cool air. This occurs when the cooler air falls and the warmer air rises.
However in forced convection, the fluid is agitated by an external force eg a fan or pump.
