There occurs no exchange of heat between a system and its surroundings in an adiabatic process. So, the change in entropy of the system is zero in this process. Justify the statement.

Text Solution

Verified by Experts

The statement is incorrect. It is applicable only for a reversible adiabatic change.
0. thus the entropy of the system increases in an irreversible adiabatic process.
