3. The quantity used to compare the hotness or coldness of bodies is known as temperature.

Step 2: Heat Transfer:

1. When two objects are kept in contact, heat is transferred from one body to another due difference in temperature.
2. When two bodies at different temperatures are brought together, heat energy is transferred from the hotter body to the colder body.

Hence, Hotter body transfer heat to a cooler body is True.
