Question

The second law of thermodynamics states:
  1. A
    ΔS_universe ≥ 0 for spontaneous processes
    Correct
  2. B
    Energy cannot be created or destroyed
  3. C
    G = H − TS
  4. D
    ΔS = 0 at equilibrium always

Correct answer

ΔS_universe ≥ 0 for spontaneous processes

Explanation

Second Law: Entropy of the universe (system + surroundings) increases for spontaneous processes (ΔS_universe > 0) and remains constant at equilibrium (ΔS_universe = 0).
