Question

Is it possible for two bodies to be in thermal equilibrium if they are not in contact?

Answer 1

Yes, it is possible for two bodies to be in thermal equilibrium if they are not in contact

Explanation:

• If two bodies are at the same temperature, they are said to be in thermal equilibrium.
• Assume, two bodies X and Y that are in contact with a heat reservoir but are not in contact with each other.
• The temperature of the reservoir will be attained by both the bodies, and they will be at the same temperature; thereby, in thermal equilibrium.
• Hence, even two bodies are not in contact, it is possible for them to be in thermal equilibrium.
