Acetone, petrol, perfume etc., existing volatile, evaporate very fast when exposed to larger surfaces. When we put some acetone, petrol, or perfume on our palms, it evaporates. During evaporationdecompositionvapourizationdistilation, particles of the liquid distilateevaporatadsorbabsorb 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 distilationvaporisationdecompositionevaporation from our palm. The palm loses heat and feels cold.
