Question

why does our palm feel cold when we put some acetone or perfume on it ?

Answer 1

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 onour palm the particles of it gain energy from our palm and evaporate quickly which causes cooling .

Answer 2

Hey how are you ?
Here's your answer!

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