What is the process called when water changes from gas to liquid?

The process when water changes from gas to liquid is known as condensation. During this process, water vapor in the air cools and transitions back into a liquid state, often forming droplets on surfaces such as grass, cars, or windows. This phenomenon is commonly observed when warm, moist air comes into contact with a cooler surface, causing the water vapor to lose energy and revert to liquid form.

Understanding condensation is important in various applications, such as meteorology, where it plays a crucial role in cloud formation and precipitation processes. It is also significant in residential and industrial settings, particularly regarding humidity control and the management of water vapor in the atmosphere.

Other processes mentioned, while related to water, refer to different phases or transformations. Evaporation is the transition from liquid to gas, sublimation involves the direct change from solid to gas, and precipitation pertains to any form of water, such as rain or snow, that falls from the atmosphere to the ground.
