What is evaporation?

Back

Evaporation is the process by which liquid turns into gas at temperatures below its boiling point. An example is water boiling.

What is freezing?

Back

Freezing is the phase change from liquid to solid.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into gas without becoming a liquid.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid turns into vapor.
