• A. The change of a substance from a liquid to a gas
• B. The change of a substance from a gas to a liquid
• C. The change of a substance from a solid to a liquid
• D. The change of a substance from a liquid to a solid

Answer: (B)

Verified step by step guidance

1. Understand that condensation is a phase change process involving a change in the state of matter.
2. Recall the common phase changes: evaporation (liquid to gas), condensation (gas to liquid), melting (solid to liquid), and freezing (liquid to solid).
3. Identify that condensation specifically refers to the transition from the gaseous phase to the liquid phase.
4. Recognize that this process typically occurs when a gas cools down and loses energy, causing molecules to come closer and form a liquid.
5. Conclude that the best description of condensation is 'the change of a substance from a gas to a liquid.'
