Question

question 1-45
which phase change involves the release of heat energy?
○ melting
○ evaporation
○ condensation
○ sublimation

Explanation:

Phase changes releasing heat are exothermic. Melting (solid→liquid), evaporation (liquid→gas), and sublimation (solid→gas) absorb heat. Condensation (gas→liquid) releases heat as particles lose energy and form bonds.

Answer:

Condensation
