In a reversible process:

A Entropy increases

B The system passes through equilibrium states and can be reversed without net change to surroundings

C Friction is present

D Heat transfer occurs across finite ΔT

✓ Correct Answer: Option B

Reversible processes are idealized — no friction, no finite temperature gradients. System and surroundings can be restored.

💡 Why is B) the correct answer?
