Chapter 10, Problem 25QP
Interpretation Introduction
Interpretation:
The reason behind the statement, ‘Pasta takes longer to cook in boiling water at a mountain camp site than at the beach,’ is to be explained.
Concept Introduction:
Vapor pressure is the measure of the tendency of a material to change into the gaseous state. It increases with temperature.
Boiling point of a liquid is the temperature at which the vapor pressure at the surface of a liquid becomes equal to the pressure surrounding the liquid.

How much heat, in joules and in calories, must be added to a 89.1 g chromium block with a specific heat of 0.450 J/g·°C to increase its temperature from 25°C to its melting temperature of 1907°C?
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
5. Suppose that after your second heating, you were impatient and did not wait until your porcelainevaporating dish to cool. Instead, you weighed it while it was still hot. How would this specifically affectthe calculated percentage of water in the compound?
