Why does our palm feel cold when we put some acetone or petrol or perfume on it?
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.
