Question

Why dose our plam feel cold when we put some acetone or petrol or perfume on it

Answer 1

because acetic acid is a weak acid and in perfume 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 .

Answer 2

HIII....

GOOD MORNING:)

HERE IS YOUR ANSWER:--------

THE REASON BEHIND THIS IS THAT IT HAPPENS DUE TO LATENT HEAT OF VAPORIZATION AS THESE MATERIALS TAKE AWAY THE HEAT FROM OUR BODY TO CONVERT INTO VAPORS WHICH GIVES US COOLING EFFECT AND OUR PALM FEEL COLD.

HOPE THIS HELPS YOU.....

HAVE A GREAT DAY AHEAD....✌
