DEF

Two bodies which are at different temperatures exchange heat in such a manner that heat flows naturally from the hotter to the colder body.

OBS

It is impossible, when unaided, to convey heat from one body to another at higher temperature; therefore in all changes, the entropy, or amount of irreversible energy of the participating bodies, increases.
