Question

how does our palm feel cold when we put acetone on it
​

Answer 1

Answer:

Solution: 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.

Answer 2

Because acetone or petrol or perfume looses their temperature and gain energy by using from surrounding air.
