Answer:

A. True

Explanation:

It is true that when there is no temperature difference between a substance and its surrounding, no net energy is transferred as heat.

The term used for this is thermal equilibrium. Thermal equilibrium occurs when two substances or even places are at the same temperature.

  • For heat to flow a gradient must be set up.
  • The gradient implies that one part is at a higher temperature than the other.
  • So, the system then works till thermal equilibrium is attained.
  • Heat generally moves from a hotter to a colder body.
  • When both bodies are at even or equal temperature, then heat stops moving.
