Answer: (D)

Verified step by step guidance

1. Understand that phase changes describe the transition of a substance from one state of matter to another, such as solid, liquid, or gas.
2. Recall that condensation is the process where a gas changes into a liquid, which typically occurs when a gas cools down and loses energy.
3. Identify the phase change options given: liquid to gas (evaporation), solid to liquid (melting), liquid to solid (freezing), and gas to liquid (condensation).
4. Match the definition of condensation with the correct phase change, which is gas to liquid.
5. Conclude that condensation is the phase change from gas to liquid.
