What is the scientific term for a gas becoming a liquid?

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

Answer: (A)

Gas becoming a liquid is condensation. This happens when a substance in its gaseous state loses enough energy (often by cooling or increasing pressure) so the moving molecules slow down enough to stick together and form a liquid. Condensation is the process behind dew forming on grass or clouds in the sky, and it releases heat as the gas turns into a liquid. Sublimation, deposition, and evaporation are other phase changes: sublimation is solid turning into gas, deposition is gas turning directly into solid, and evaporation is liquid turning into gas.
