Question

our palm feel cool when we kept acetone on it but it doesn't show coolness when there is water drops. why​

Answer 1

Explanation:

When we put some acetone or petrol or perfume on our palm, it evaporates. During evaporation, particles of the liquid absorb energy from the surface of the palm to compensate for the loss of energy, making the surroundings cool. The acetone, petrol or perfume take this latent heat of vaporisation from our palm.

Answer 2

Answer:

ACETONE EVAPORATES VERY QUICKLY SO IT GIVES A COOL FEELING WHERE AS WATER EVAPORATES AT 100 DEGREES THUS IT FAILS TO GIVE COOLING
