Question

why we feel cool on putting a drop of acetone on our palm

Answer 1

We feel cool on putting a drop of acetone on our palm because it converts into vapour at a fast rate this increases the liquid molecules around in it.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 .
