That's correct! When a gas changes to a liquid, it's called condensation.

Here's a simple explanation:

* Gas particles are spread far apart and move freely.

* Cooling the gas slows down the particles, making them move closer together.

* When the particles get close enough, they attract each other and form a liquid.

Think about these examples of condensation:

* Dew forming on grass: Water vapor in the air cools down at night, condensing into liquid water droplets.

* Fog: Water vapor in the air cools and condenses into tiny water droplets, creating fog.

* Steam from a kettle: Water vapor in the steam cools down, condensing into tiny water droplets.
