Pick out the wrong statement.
A. The net change in entropy in any reversible cycle is always zero
B. The entropy of the system as a whole in an irreversible process increases
C. The entropy of the universe tends to a maximum
D. The entropy of a substance does not remain constant during a reversible adiabatie change
Answer: Option D
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.
