## Definition

the process of a liquid turning into a gas. This usually happens when the liquid gets warmer, like when water disappears from a puddle on a sunny day.

For teachers: the process by which a substance in a liquid state changes into a gaseous state due to an increase in temperature or pressure. Often occurs at the surface of the liquid before reaching its boiling point.

## Examples

- Heat from the sun causes the evaporation of water from the lake.
- The chef reduced the sauce through slow evaporation to concentrate the flavors before serving.
- In arid climates, the rate of evaporation often exceeds the annual rainfall, leading to the gradual salination of local soil and water sources.
