Here's why:
* Boiling point is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid, and the liquid changes into a vapor.
* Evaporation occurs when molecules at the surface of a liquid gain enough kinetic energy to overcome the intermolecular forces holding them in the liquid state. These molecules escape into the surrounding air as a gas.
Key points about evaporation:
* It happens at any temperature below the boiling point.
* It is a slower process than boiling.
* It occurs from the surface of the liquid.
* The rate of evaporation depends on factors like temperature, surface area, and humidity.
Examples of evaporation:
* Water drying on a wet surface.
* A puddle disappearing on a hot day.
* Perfume evaporating from your skin.
