Question

Clausius inequality states that for any cyclic process:
  1. A
    ∮dQ/T ≥ 0
  2. B
    ∮dQ/T ≤ 0
    Correct
  3. C
    ∮dQ/T = 0
  4. D
    ∮dQ = 0

Correct answer

∮dQ/T ≤ 0

Explanation

Clausius inequality: ∮dQ_rev/T = 0 (reversible) and ∮dQ_irrev/T < 0 (irreversible). Combined: ∮dQ/T ≤ 0.
