Hola Friend

Here is your answer..............

Acetone is highly sublimable. it converts into vapour at a fast rate. this increases the liquid molecules around it in vapour phase thus our palm feel cold.

Because acetone or petrol or perfume looses their temperature and gain energy by using from surrounding air.
