Question

which change of state involves a release of energy?
boiling
condensation
melting
sublimation

Explanation:

Changes of state that release energy are exothermic processes, where particles lose energy and move closer together. Condensation is the transition from gas to liquid, during which particles slow down and release thermal energy. Boiling, melting, and sublimation are endothermic processes that require energy input to break intermolecular bonds and move particles apart.

Answer:

B. condensation
