Question

vaporization condensation melting sublimation deposition freezing occurs when a substance absorbs energy as it changes phases occurs when energy is released as a substance undergoes a phase change exothermic endothermic

Explanation:

Exothermic phase - changes release energy. Condensation (gas to liquid), deposition (gas to solid), and freezing (liquid to solid) are exothermic as they involve the substance losing energy. Endothermic phase - changes absorb energy. Vaporization (liquid to gas), sublimation (solid to gas), and melting (solid to liquid) require energy input.

Answer:

Exothermic: condensation, deposition, freezing
Endothermic: vaporization, sublimation, melting
