A process in which a gas changes into a liquid is ___.

vaporization

sublimation

freezing

deposition

condensation

condensation

A process in which a gas changes into a liquid is called condensation.

The correct answer is condensation.

To determine the correct answer, you can break down the question and consider the different processes that involve changes of state.

Vaporization refers to the process of a liquid changing into a gas.

Sublimation refers to when a solid changes directly into a gas without passing through the liquid state.

Freezing is the process in which a liquid changes into a solid, such as when water turns to ice.

Deposition is the reverse of sublimation; it occurs when a gas changes directly into a solid without passing through the liquid state.

Condensation, on the other hand, is the process in which a gas changes into a liquid. This occurs when a gas loses energy and its particles slow down, coming closer together to form a liquid state.

Therefore, the correct answer is condensation.
