Final answer:
The overall direction of heat transfer is from the higher-temperature object to the lower-temperature object.
Step-by-step explanation:
When thermal energy is transferred from one place or object to another, the overall direction of heat transfer is from the higher-temperature object to the lower-temperature object. This means that heat is transferred from Object A to Object B. It is a natural process that occurs in order to reach thermal equilibrium, where both objects are at the same temperature.
