Verified step by step guidance1
Identify the process described: water vapor (gas) turning into liquid water on a cold surface.
Recall the definitions of phase changes: Evaporation is liquid to gas, Condensation is gas to liquid, Sublimation is solid to gas, and Deposition is gas to solid.
Match the described change (gas to liquid) with the correct term, which is Condensation.
Understand that condensation occurs when water vapor cools and loses energy, causing molecules to come closer and form liquid droplets.
Conclude that the change of state represented in the model is Condensation.
