Heya!!Here is your answer friend ⤵⤵
➡The conversion of water ( liquid ) to water vapour ( gaseous ) on heating is called EVAPORATION.
➡Evaporation causes a cooling effect = This is because when the substance at evaporates , they gain energy from the surroundings and leave a cooling effect behind .
Example :➡ when you put some Acetone on your palm , it gives a cooling effect
➡ Water in an earthen pot stays cool due to evaporation.
↔↔Factors affecting evaporation are
1. Wind speed
2. Temperature
3. Humidity
4. Surface area

Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surroundingcool.
Example :
1.when we spray a deo onour hand.
2.Aetone
