Which process occurs when water vapor cools and changes into a liquid?

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

Answer: (B)

Condensation is the process where water vapor becomes liquid as it loses energy and cools. When gas cools, its particles slow down, and the attractive forces allow them to come closer until they form liquid water. This explains why fog, dew, and clouds form. Evaporation is the change from liquid to gas when heated, precipitation is rain or other forms of water falling to the surface after atmospheric processes, and sublimation is a solid turning directly into a gas.
