Question

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

Answer 1

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. The acetone, petrol or perfume take this latent heat of vaporisation from our palm. The palm loses heat and feels cold.
