Answer: It is because of evaporation.
Explanation: Substances like acetone, ethyl, alcohol, petrol or perfume are volatile substances. Such substances vaporise very quickly. We know that evaporation causes cooling. When a liquid evaporates, it takes the latent heat of vaporization from 'anything' it touches. By losing heat this 'anything' gets cooled. Thus, when those substances mentioned above touch our palm, they take up latent heat and evaporates, making our palm feel cool
