Answer 1

Option (c) is the correct answer.

Explanation: When two substances does not exchange any energy with each other then they are said to be in thermal equilibrium with each other. This means the temperature of both the substances will be equal, that is why, there is no exchange of energy between them. Thus, we can conclude that when the objects have the same temperature then you can tell the two objects are in thermal equilibrium.
