Part A:
What mass of water must evaporate from the skin of a 69.0 kg man to cool his body 0.950 ?C? The heat of vaporization of water at body temperature (37.0 ?C) is 2.42×106J/kg. The specific heat of a typical human body is 3480 J/(kg?K).
m=____________kg
Part B:
What volume of water must the man drink to replenish the evaporated water? Compare this result with the volume of a soft-drink can, which is 355 cm3
V=____________cm3
