- 22) Evaporation of sweat requires energy and thus take 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 (590g) 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 therm properties of sweat are the same as for water. Us, liquid water = 4.184 J/g °C Cs, steam= 1.84 J/g °C C3, ice = 2.09 /g °C AHvap = 40.67 kJ/mol at 36.6 °C. %3D A Hus = 6.01 kJ/mol A) 1420 kJ B) 81 kJ C) 1150 kJ 23) Based on the graph shown below, choose the correct statement about sublimation?
