During phase change, entropy
- A remains constant
- B always increases
- C always decreases
- D may increase or decrease
Answer & Solution
Correct Answer
(D) may increase or decrease
Step-by-step Solution
Detailed explanation
The entropy of a system during phase change (phase transition) increases, if the phase transition is towards higher internal energy (e.g., during melting) and decreases if the phase transition is towards lower internal energy (e.g., during freezing). Therefore, during phase…
