Evaporation

Evaporation

What is it?

Evaporation is when a liquid becomes a gas. This is usually done by heating the liquid. Evaporation is the opposite of condensation.

Give me an example!

Have you ever watched steam rise from a pot of boiling water? The water in the pot is a liquid -- and as it is heated, it begins to evaporate and become steam, which is a gas.
