Question

Air is warmer near the ceiling than the floor.
Is it convection, conduction or radiation.

Answer 1

Answer:

Convection is the transfer of heat by the physical movement of hot masses of air. As air is heated, it expands (as do all objects). As it expands, it becomes lighter then the surrounding air and it rises. (This is why the air near the ceiling of a heated room is warmer than that near the floor.)
