endothermic - evaporation of the chloroform removes energy from the skin surface and the skin feels cooler. This is how the body cools itself when you perspire.

There is no reaction, just a change of state, which is endothermic. The only "reaction" might be that they get liver damage/liver cancer from having contact with a nasty carcinogen!

Could be endothermic, but most likely mere evaporation of a volatile solvent.
