Energy Transfer

Heat Transfer.

Heat is transferred naturally from a substance with a higher temperature
to a substance with a lower temperature.

Heat can be transferred in three ways.

1.  Conduction - by a substance which does not move (solids).

2.  Convection - by a substance which moves (liquids and gasses).

3.  Radiation - infra-red radiation is exchanged between all substances.
