These liquids vapoeise readily upon taking the heat from the skin surface. Faster vaporisation means faster consumption of heat, this is sensed by the skin. Thus cooling sensation.

Acetone,petrol or perfume has low boiling point.when we put these substance on palm it gains the energy from the palm and evaporates quickly and our palm feels cold

Since the boilingbpoint of these substances are low when we put them on our palm it absorbs the heat of our body and is evaporated. The loss of heat resultrin the sensation of cooling.
