Here's how it works:

* Decreasing Temperature: When the temperature of a gas decreases, the molecules slow down. This means they have less kinetic energy and move around less.

* Increased Intermolecular Forces: As the molecules slow down, the attractive forces between them (intermolecular forces) become more significant.

* Closer Proximity: The molecules start to clump together and get closer to each other.

* Liquid Formation: Eventually, the molecules become close enough that they are attracted to each other strongly enough to form a liquid.

Here are some examples of condensation:

* Dew forming on grass: The warm, humid air cools down overnight, causing water vapor to condense into tiny water droplets.

* Fog forming: When warm, moist air encounters a cooler surface, the water vapor condenses into tiny water droplets suspended in the air.

* Water droplets forming on a cold glass: The warm, humid air surrounding the glass cools down, causing the water vapor to condense on the glass.
