Which process occurs when water vapor cools and becomes a liquid?

• A. Evaporation
• B. Precipitation
• C. Condensation
• D. Transpiration

Answer: (C)

Condensation is the process in which water vapor cools and changes into a liquid. When water vapor loses enough energy, its molecules move closer together and form liquid droplets. This is why clouds form, and why dew appears on grass in the morning. Evaporation is the transformation of liquid water into water vapor when energy is added. Precipitation is the falling of liquid water or ice from clouds. Transpiration is the release of water vapor from plant leaves.
