evaporate

Definition

Evaporation is the process by which a liquid changes into a gas. This happens when the molecules of the liquid have enough energy to break away from the surface of the liquid and enter the air.

Evaporation can happen at any temperature, but it happens more quickly at higher temperatures. This is because the molecules of a liquid have more energy at higher temperatures.

Evaporation is important for a number of reasons. It helps to cool the Earth's surface, and it helps to distribute water vapour in the atmosphere. Water vapour is the gas form of water, and it is the main component of clouds.
