Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 kJ

Chapter 0, Problem 103

(choose chapter or problem)

Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 kJ per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by 0.50 C, if the mass of the body is 95 kg and its heat capacity is 4.0 J/g C. (Assume that the heat transfer is 100% efficient.)
