Answer 2

Hey there!✌
Here is your answer...⤵⤵

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