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 70.0-kg man to cool his body 1.00 C°? The heat of vaporization of water at body temperature (37°C) is 2.42 X 10° J/kg-K. The specific heat of a typical human body is 3480 J/kg K b. (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).
