Answer 2

It converts into vapour at a fast rate. this increases the liquid molecules around it in vapour phase thus our palm feel cold. acetone,petrol or perfume has very low boiling temperature. when we put some acetone on our palm the particles of it gain energy from our palm and evaporate quickly which causes cooling .
