Question

explain entropy change during phase change

Answer 1

Answer:

every system in the universe experiences entropy change

Explanation:

every particle has tendency to lower their entropy

Answer 2

Answer:

The entropy of a system undergoing a phase transition increases if the phase transition is towards higher internal energy (e.g., melting) and decreases if the phase transition is towards lower internal energy (e.g., freezing). The change in the entropy of the surroundings is of opposite sign.
