NEET Physics Entropy Assertion Reason Question
Assertion (A): Entropy change can differentiate between reversible and irreversible processes. | Reason (R): In isothermal expansion of an ideal gas, the total entropy change is zero for a reversible process.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
According to the NCERT context, entropy change (∆S) can distinguish between reversible and irreversible processes, as ∆S total is not zero for irreversible processes, whereas it is zero for reversible processes under isothermal conditions.
