Entropy change for an irreversible process taking system and surrounding together is___________________?
Correct answer: B. > 0
- A. 0
- B. > 0
- C. < 0
- D. None of these
Explanation
For an irreversible process, entropy is generated, so the entropy change of the combined system and surroundings, or the universe, is positive. A reversible process would have zero total entropy change.
