A runner generates 418 kJ of energy per kilometerfrom the cellular oxidation of food. The runner's body mustdissipate this heat or the body will overheat. Suppose that sweatevaporation is the only important cooling mechanism. If youestimate the enthalpy of evaporation of water as 44kJ/mol and assume that sweat can be treated as water,describe how you would estimate the volume of sweat that would haveto be evaporated if the runner runs a 10-km race.
