Answer 2

Answer:

Our palm feels cold because these substances are highly volatile.

Explanation:

The palm feels cold when we add some ""acetone"" or ""petrol"" or ""perfume"" on it because as soon as we apply these substances they start evaporating.

All of these substances are highly volatile. Because of the latent heat of vaporization, these materials extract heat from our body and vaporize it which produces a cooling effect and the palm feels cold.

These substances convert the energy in the palm into vapors.
