Question

which process requires the absorption of energy?
freezing
deposition
melting
condensation

Explanation:

Phase changes that require energy (endothermic) involve moving to a higher energy state (solid→liquid→gas). Freezing (liquid→solid), deposition (gas→solid), and condensation (gas→liquid) release energy (exothermic). Melting (solid→liquid) needs energy to break intermolecular bonds.

Answer:

melting
