here is your answer ✌✌

conversion of matter from liquid state to vapour at any temperature below its boiling point is called evaporation.

evaporation is useful because it causes cooling etc

eg: during summer we perspire more( sweat) evaporation takes away the heat from the body means the heat energy present in sweat is exposed in air and we we feel cool

it is surface phenomenon that is evaporation takes place at surface of liquid only

it is spontaneous process.
