Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by 0.30, if the mass of the body is 94 and its heat capacity is 4.0 . (Assume that the heat transfer is 100 efficient.)
