This is the difference between evaporation and vaporization

Evaporation happens at the surface of a liquid
Vaporization happens throughout the liquid as the liquid boils

400

This is one factor that affects evaporation

temperature or surface area, or humidity, or wind,

Evaporation of sweat cools you down because....

It absorbs heat from your skin for the liquid (sweat) to turn to gas. So it removes heat from you/your body to change sweat to a gas....
