What happens when you pour some acetone on your palm ???..
Acetone takes up the heat energy from the palm to vaporize as it requires latent heat vaporisation to change from liquid state to vapour state. The hand loses heat and gets cooled. This is the example of cooling by evaporation.
@roman_sherin: very good attempt. keep it up!thumbs up!
