What happens when matter changes state from gas to liquid?

• A. Condense
• B. Vaporize
• C. Liquefy
• D. Depressurize

Answer: (A)

Condensation is the process by which a gas becomes a liquid. It happens when the gas loses enough energy—usually by cooling or by being compressed—that the particles slow down and stick together to form a liquid. As this energy is released, latent heat is given off. You can see condensation in everyday life when water vapor turns into droplets on a cold surface, or in clouds where warm air cools and the water vapor clumps into droplets. In devices like air conditioners, vapor becomes liquid in the condenser as heat is released to the surroundings. While liquefy can describe turning a gas into a liquid, condensation is the standard term for this specific gas-to-liquid change. Vaporize is the opposite, turning liquid into gas, and depressurize isn’t describing a state change by itself.
