Here's a simplified explanation:
* Gas: Molecules in a gas are far apart and move freely.
* Cooling: As you cool a gas, the molecules slow down and move closer together.
* Condensation: When the molecules are close enough and slow enough, they start to attract each other and form a liquid.
Think of it like this: Imagine you have a bunch of bouncy balls in a large room (gas). As you cool the room, the balls move slower and start to bunch together (liquid).
