Two bodies at different temperatures T1 and T2, if brought in thermal Contact, do not necessarily settle of the mean temperature (T1 + T2)/2.Why?

Answer»

In thermal contact, teat flows from the body at highre temperature to the body at lower temperature till temperatures become equal. The final temperature can be the mean temperature (T1 + T2)/ 2 only when thermal capacities of the bodies are equal.
