When evaporation occurs then than the liquid (mostly water) absorbs all the heat from the surroundings and take it with it and we feel cool.evaporation causes cooling effect because the heat energy is abosorbed by surrounding particles.

Ex : when we spray a deo on our hand.
Ex 2 : Aetone
Reason for the above examples : the deo and the nail poslish remover are volatile substance. they absorb latent heat of vaporisation from our hand and gets converted rapidly into gaseous form. hence we feel cold.

.THIS IS ALSO AN EXAMPLE OF CONDENSATION.
