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

condensation

melting

freezing

sublimation

deposition

vaporization

The correct answer is freezing.

The process in which a liquid changes into a solid is called freezing.

The correct answer is freezing.

To determine the correct answer, it is important to understand the process of each option and then identify the correct process.

1. Condensation: This is the process in which a gas changes into a liquid. For example, when water vapor in the air cools and turns into liquid water droplets on a cold surface.

2. Melting: This is the process in which a solid changes into a liquid. For example, ice melting and turning into water when heated.

3. Freezing: This is the process in which a liquid changes into a solid. For example, when water freezes, it turns into ice.

4. Sublimation: This is the process in which a solid changes directly into a gas without passing through the liquid stage. For example, solid dry ice (frozen carbon dioxide) sublimates and turns directly into carbon dioxide gas.

5. Deposition: This is the process in which a gas changes directly into a solid without passing through the liquid stage. For example, when water vapor in the air changes into frost or ice crystals on a cold surface.

From the given options, the process in which a liquid changes into a solid is freezing.
