Assertion : Two bodies at different temperatures if brought in thermal contact do not necessary settle to the mean temperature
Reason : The two bodies may have different thermal capacities.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
A
When two bodies at temperature `T_1 and T_2` are brought in thermal contact, they do settle to the mean temperature `(T_1 + T_2)//2`.
They will do so, in case the two bodies were of same mass and material, i.e., same thermal capacities. In other words, the two bodies may be having different thermal capacities that are why they do not settle to the mean temperature, when brought together.
