Condensation

Condensation

What is it?

Condensation is when a gas turns into a liquid. This is done by cooling the gas. Condensation is the opposite of evaporation.

Give me an example!

Have you ever seen how car windows fog up on a cold day? That's an example of condensation. The water vapor in your breath is a gas, and as it comes from inside your warm body, it condenses into droplets of liquid on the cold inside surface of the car windows. If it's cold enough, that liquid will freeze on the window and become frost.
