The process in which a substance changes from a gaseous state to a liquid state is called condensation.

Here's a breakdown:

* Gas: In a gaseous state, molecules are spread far apart and move freely with high kinetic energy.

* Condensation: As the gas cools down, the kinetic energy of the molecules decreases, causing them to slow down and move closer together. This results in the gas changing into a liquid.

Factors that influence condensation:

* Temperature: Lower temperatures favor condensation.

* Pressure: Increased pressure forces gas molecules closer together, promoting condensation.

* Surface area: A larger surface area provides more sites for condensation to occur.
