Which process describes the change of a substance from a gas to a liquid?

The transition of a substance from a gas to a liquid is known as condensation. This process occurs when water vapor in the air cools down and loses energy, allowing the molecules to come closer together and form liquid droplets. It is most commonly observed when humidity in the air condenses on a cooler surface, such as dew forming on grass in the morning or water droplets forming on a cold beverage.

In contrast, evaporation refers to the process of a liquid turning into vapor, while freezing describes the transition of a liquid into a solid. Sublimation is the process in which a solid turns directly into a gas, bypassing the liquid phase altogether. Understanding these processes is crucial for studying phase changes in matter and their implications in various scientific fields.
