Evaporation of sweat is an important mechanism for temperature control in some warm-blooded animals. a) what mass of water must evaporate from the skin of a 70 kg man to cool his body 1.00 degree Celsius? The heat of evaporation of water at body temperature 37 degrees Celsius is 2.42x 10^6 J/kg. K. the specific heat of a typical human body is 3480J/kg. K b) what volume of water must the man drink to replenish the evaporated water? Compare to the volume of a soft drink can (355 cm^3).
