which phase change is exothermic? a condensation b melting c sublimation d vaporization
Answer
# Brief Explanations:
Exothermic phase - changes release heat. Condensation is the change from gas to liquid and releases heat. Melting (solid - to - liquid) is endothermic as it requires heat. Sublimation (solid - to - gas) and vaporization (liquid - to - gas) are also endothermic processes as they require energy input to change the state.
# Answer:
A. condensation
