Answer: Heat
Explanation: The transfer of heat or thermal energy occurs when there is a difference in temperature in a object or both. Heat moves from objects with higher temperature to objects with lower temperature. If both objects reaches the same temperature then they are said to be in thermal equilibrium, which means that there will be no more heat transfer between the objects.
