The process by which a gas converts to a liquid when the temperature decreases is called?

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

Answer: (D)

Condensation is the process by which a gas becomes a liquid as it cools. When a gas loses energy, its molecules slow down and the attractive forces between them pull them into a coordinated liquid state. This release of energy accompanies the phase change. Evaporation is the reverse: a liquid turning into a gas when it’s heated or when pressure is reduced. Sublimation is a solid turning directly into a gas, skipping the liquid phase. Precipitation refers to liquid water or ice falling from the atmosphere, not the direct gas-to-liquid transition.
