Its also known as the cooling phenomenon of evaporation
In simple, when the liquid turns into gas it needs heat to evaporate. ... As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid decreases. This phenomenon is also called evaporative cooling. This is whyevaporating sweat cools the human body.
hope its helpful
