When a gas turns into liquid, the process is called:

Condensation is the process where a gas changes into a liquid. This happens when gas cools down and loses energy. When the particles in the gas slow down enough, they come closer together and form a liquid. For example, water vapor in the air turns into tiny water droplets on a cold glass or on the surface of leaves in the morning. This process is important in the water cycle, helping to form clouds and rain. It is the opposite of evaporation, where liquid turns into gas by gaining heat. Sublimation is when a solid changes directly into gas, skipping the liquid stage, like dry ice turning into carbon dioxide gas. Solidification is when a liquid becomes a solid, such as water freezing into ice. Understanding condensation helps explain many everyday weather and science phenomena.
