Verified step by step guidance1
Understand that condensation is a phase change process involving a change in the state of matter.
Recall the common phase changes: melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), sublimation (solid to gas), and condensation (gas to liquid).
Identify that condensation specifically refers to the transition from the gaseous phase to the liquid phase.
Eliminate other options by matching their descriptions to known phase changes: solid to gas is sublimation, liquid to gas is vaporization, and liquid to solid is freezing.
Conclude that the best description of condensation is 'The process in which a gas changes into a liquid.'
