Here's what happens:

* Energy Loss: Gas molecules are constantly moving and colliding. When they lose energy, they slow down.

* Attraction Increase: As molecules slow down, the attractive forces between them become stronger.

* Closer Proximity: The molecules come closer together.

* Liquid Formation: When the molecules are close enough and moving slowly enough, they form a liquid state.

Visual Example: Imagine steam from a hot shower. The steam is water vapor, a gas. As it touches the cold bathroom mirror, the water vapor molecules lose energy to the mirror. They slow down, clump together, and form tiny water droplets on the mirror – condensation!

Here are some key things to remember about condensation:

* Heat is released: Energy is released during condensation because the molecules lose kinetic energy.

* It's the opposite of evaporation: Evaporation is the change of a liquid to a gas.

* It happens all the time: Condensation is a common occurrence in nature. We see it in dew on grass, fog, clouds, and rain.
