Physics, Latent heat problem!!!?

An alcohol rub can rapidly decrease body (skin) temperature. (a) THis is because of (1) the cooler temperature of the alcohol, (2) the evaporation of alcohol, (3) the high specific heat of the human body. (b) To decrease a 65-kg person by 1.0 ˚C, what mass of alcohol must be evaporated from the person's skin?... show more An alcohol rub can rapidly decrease body (skin) temperature.

(b) To decrease a 65-kg person by 1.0 ˚C, what mass of alcohol must be evaporated from the person's skin? Ignore the heat involved in raising the temperature of alcohol to tis boiling point (why?) and approximate the human body as water.

Thank you! :)
