Physics Heat

1)
Heat always flows from a hotter body to a colder body. The coffee is hotter than the air in the surroundings. When the hot coffer is stirred, the input energy by stirring is less than the energy loss to the surroundings. Consequently, the hot coffer would be cooled down.


2)
The statement is incorrect.

Heat always flows from a hotter substance to a colder substance. Therefore, the statement should be corrected as:
"Heat always flows from a body with more average internal energy per unit volume to a body with less average internal energy per unit volume."

Consider the case that a very small hotter body in contact with a very large colder body. Heat flows from the very small hotter body to the very large colder body due to their temperature. Think about that the very small hotter body has more average internal energy per unit volume, but has less amount of internal energy.
