Which process describes gas changing into a liquid?

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

Answer: (A)

Condensation is the process by which a gas becomes a liquid. It happens when the gas loses energy (often by cooling or pressure increasing), causing the fast-moving molecules to slow down and come together into a liquid. You can see it in everyday examples like dew forming on grass or fog on a cold window. The other options describe different phase changes: evaporation is liquid turning into gas, sublimation is solid turning directly into gas, and freezing is liquid turning into solid.
