Damp clothes can be fatal on a mountain Suppose the clothing you were wearing had absorbed 1.2 kg of water, and a cold wind dried it. a) What heat loss does the body have to make good? b) What weight of sucrose would have to be consumed to replace that loss? c) Suppose your body did not make good the heat loss, what would your temperature be at the end of the evaporation? Assume your heat capacity is the same as that of water. AH (Water) = 44 kJ molt (note at constant pressure heat may be equated to enthalpy), AH':{sucrose) = -5.64 x 10^ J moli". M(sucrose) = 342.3 g mor! Where is the temperature, q is the heat and C is the heat capacity. The molar heat capacity of water is 75.5 J K mot'. Assume a body weight of 70 kg.
