Humans cool off by perspiring; the evaporating sweat removes heat from the body. If the skin temperature is 35.0°C and the air temperature is 15.6°C, what is the entropy change of the universe due to the evaporation of 215 mL of sweat? Take the latent heat of vaporization of sweat to be the same as that for water (Lv = 2,256 J/g). (You may also assume that the density of sweat is equal to that of water.)
