Solids, Liquids, Gases

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming droplets.

Front

What is sublimation?

Back

Sublimation is the phase change in which a solid turns directly into a gas without first becoming a liquid.

Front

What happens to particles when the temperature of matter increases?

Back

When the temperature of matter increases, the particles speed up and move farther apart.

Front

What is melting?

Back

Melting is the process where a solid turns into a liquid when it is heated.

Front

What is evaporation?

Back

Evaporation is the process by which a liquid turns into a gas, usually at the surface of the liquid.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at any temperature and only at the surface, while boiling occurs throughout the liquid at a specific temperature.

Front

What is freezing?

Back

Freezing is the process where a liquid turns into a solid when it is cooled.

Front

What is deposition?

Back

Deposition is the phase change in which a gas turns directly into a solid without becoming a liquid first.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving evaporation, condensation, and precipitation.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state (solid, liquid, gas) to another.
