Question

Q. What happens when you pour some ether or acetone on your palm ?

Answer 1

acetone takes up the heat energy from the palm to vaporise as it  requires latent heat vaporisation to change from liquid  state to vapour state.the hand looses heat and become cool.this is a example of cooling by evaporation

Answer 2

Answer:

Acetone has very low boiling point. When we put some acetone on our palm, the particles of it gain energy form our palm and evaporate quickly which causes cooling
