Front

What is condensation?

Back

Condensation is the process where a gas turns into a liquid, often when it cools down.

Front

What happens during freezing?

Back

Freezing is the process where a liquid turns into a solid as it loses heat energy.

Front

What is evaporation?

Back

Evaporation is the process where a liquid changes into a gas, usually when it is heated.

Back

Gas is the state of matter that has an indefinite shape and an indefinite volume.

Front

What are the two phase changes that take away energy?

Back

Freezing and condensation are the two phase changes that take away energy.

Front

What is melting?

Back

Melting is the process where a solid turns into a liquid as it gains heat energy.

Front

What is an example of condensation?

Back

An example of condensation is water droplets forming on a cold glass.

Front

What is the difference between evaporation and boiling?

Back

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