KMT and Properties of Gases
1. Name the postulates of the kinetic molecular theory and state whether or not
you believe they do a good job of describing how real gases behave.
2. Based on the postulates of the kinetic molecular theory, give the conditions of
pressure and temperature that you believe would cause a real gas to best
simulate an ideal gas. Explain your answer.
3. Convert the following:
a. 125 kPa to atm
g. 123 C to K
b. 782 mm Hg to atm
h. -12.0 C to K
c. 2.16 atm to mm Hg
i.
393 K to C
d. 0.925 atm to kPa
j.
1837 C to K
e. 218 kPa to mm Hg
k. 33 K to C
f. 712 mm Hg to kPa
4. Determine the pressure for the gas in each of the following barometers in mm
Hg. Then convert each pressure to atm and kPa.
