Evaporation of sweat requires energy and thus takes excess heat away from
the body. Some of the water that you drink may eventually be converted into
sweat and evaporate. If you drink a 20-ounce bottle of water that had been in the
refrigerator at 3.8 °C, how much heat is needed to convert all of that water into
sweat and then to vapor?? (Note: Your body temperature is 36.6 °C. For the
purpose of solving this problem, assume that the thermal properties of sweat are
the same as for water.)

this? Explain it in words. Actual calculations are not needed, but can be included.
