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/evaporation (liquid to gas), and condensation (gas to liquid).
Identify that condensation specifically refers to the transition from the gaseous phase to the liquid phase.
