Assertion : In an isolated system the entropy increases.
Reason : The processes in an isolated system are adiabatic.

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:
B
In an isolated system there is no exchange of heat so entropy will always increase as the process is spontaneous. Adiabatic process happens in an isolated system as q=0.
