1.	Why does our plam feel cold when we put acetone or perfume on it?
Answer» Acetone, petrol, perfume etc., being volatile, evaporate very fast when exposed to larger surfaces. 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. Hence, our palm feels cold when we put some acetone or petrol or perfume on it. Because it loses energy in evaporation and it takes from our palm that\'s why we feel cold while applying acetone or perfume on our palm
