It seems like there's a misunderstanding in the question. Both gases and vapors can condense. Here's why:

* Gas: A gas is a substance in its gaseous state where the molecules are far apart and move freely.

* Vapor: A vapor is a gaseous form of a substance that is normally a liquid or solid at room temperature.

Condensation is the process where a gas or vapor changes into a liquid. This happens when:

* The temperature decreases: As the temperature drops, the molecules slow down and lose energy, allowing them to come closer together.

* The pressure increases: Higher pressure forces the molecules closer together, increasing the likelihood of them forming a liquid.

Examples:

* Water vapor in the air condenses into liquid water droplets on a cold surface.

* Steam escaping from a boiling pot condenses into water droplets when it hits the cooler air.
