Question

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

Answer 1

Answer:

So when we put some acetone, petrol, or perfume on our palm, they evaporate. During the Evaporation process, the particles of liquids absorb energy from the surface of the palm, as we all know that “Energy is neither created nor destroyed”, the loss of energy results in making the surroundings cool.
