Entropy change in case of reversible adiabatic process is

A. Minimum

B. Zero

C. Maximum

D. Indeterminate

Answer: Option B

Solution (By Examveda Team)

We know for reversible process $$TdS = \delta Q$$ and since in adiabatic process $$\delta Q = 0 \Rightarrow TdS = 0$$ so reversible adiabatic process is an isentropic process.
