Entropy change for an irreversible isolated system is__________________?
Correct answer: B. > 0
- A. ∞
- B. > 0
- C. < 0
- D. 0
Explanation
An isolated system has no heat or mass exchange, so the entropy balance reduces to entropy generation. Irreversibility makes this generation strictly positive, hence ΔS > 0.
