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?
Gas
Liquid
sublimation
Solid
A) Sublimation is a phase transition from solid to gas
B) According to Hess Law, AHsub can be calculated as sum of AHvap and AHUS
C) Both A and B are correct
(a) Consider a substance where the intermolecular forces hold the molecules in fixed rigid positions. What is the process called when enough heat has been added to the substance so that the molecules begin to flow? (b) Consider a substance where the intermolecular forces hold the molecules in close contact with each other, but the molecules can flow. What is the process called when enough heat has been added to the substance so that the molecules escape each other? (c) Consider a substance where the intermolecular forces hold the molecules in fixed rigid positions. What is the process called when enough heat has been added to the substance so that the molecules can escape each other?
Water is a good solvent for many substances. What is the molecular basis for this property, and why is it significant?
