Melting of wax is accompanied with ______________ in entropy?
Correct answer: A. Increase
- A. Increase
- B. Decrease
- C. No change
- D. None of these
Explanation
The liquid phase of wax is more disordered than its solid phase, so melting increases molecular disorder and entropy. For a reversible phase change, this is also consistent with ΔS = ΔH_fus/T > 0.
