What is the process called when vapor changes to a liquid?

The process when vapor changes to a liquid is known as condensation. This occurs when water vapor in the air cools down and transitions back into its liquid form, often forming droplets. This phenomenon can be observed in everyday life, such as when steam from a hot shower condenses on cool bathroom mirrors or when dew forms on grass in the morning.

The other terms listed refer to different processes: sublimation refers to the direct transition from a solid to a vapor without passing through the liquid state, evaporation describes the process of liquid turning into vapor, and melting is the transition from a solid to a liquid state. Understanding these definitions highlights the distinct nature of condensation as a process contrary to the others mentioned.
