Question

What happens when you put some acetone on your palm​

Answer 1

Answer:

Acetone is highly sublimable. It converts into vapour at a fast rate which increases the liquid molecules around it in the vapour phase. Thus when poured on the palm, it absorbs the heat in our palm and evaporates quickly leaving a cool sensation. Hence when we pour some acetone on our palm, it feels cold.

Answer 2

The palm starts to feel colder. It is because the acetone soaks up heat energy from your palm and evaporates. The heat it absorbed is also referred to as the Latent Heat of Vaporisation.
