Question

The flow of thermal enery is called...?

Answer 1

Depending on how it flows, it could be called either conduction, radiation, or convection.

Explanation:

Conduction requires contact between the hot and the cooler object. Ex: That is how water in a pan on the stove is heated.

Radiation involves electromagnetic radiation. Ex: Heat energy from the sun reaches Earth via radiation.

Convection involves warmer molecules moving to cooler areas. Ex: The heating system of some buildings have fans to blow heated air out from the system to the rooms.
