Simple Gas Laws
Directions: Match each chemist to one of the gas laws below:
_____ 1. The pressure of a gas is inversely proportional
to its volume.
a. Gay-Lussac
_____ 2. The sum of the partial pressures of gases in a
mixture is equal to the total pressure of the mixture.
b. Graham
_____ 3. The pressure of a fixed mass of gas at constant
volume varies directly with the Kelvin temperature.
c. Boyle
_____ 4. The volume of a gas is directly proportional to
its temperature.
_____ 5. the rate of gas movement is inversely proportional
to the square root of the molar mass
d. Dalton
e. Charles
6.
A 24 L sample of a gas at fixed mass and constant temperature exerts a pressure of
3.0 atm. What pressure will the gas exert if the volume is changed to 16 L?
7.
A sample of argon gas occupies a volume of 950 mL at 25.0oC. What volume will
the gas occupy at 50.0oC if the pressure remains constant?
8.
A sample of air has a volume of 140.0 mL at 67oC. At what temperature would its
volume be 50.0 mL at constant pressure?
9. A sample of gas at 47oC and 1.03 atm occupies a volume of 2.20 L. What volume
would this gas occupy at 107oC and 0.789 atm?
10. The pressure on a gas at -73oC is doubled, but its volume is held constant. What will
the final temperature be in degrees Celsius?
11. A gas has a volume of 450.0 mL. If the temperature is held constant, what volume
would the gas occupy if the pressure were reduced to one-fourth of its original value?
12. A sample of oxygen that occupies 1.00 x 106 mL at 575 mm Hg is subjected to a
pressure of 1.25 atm. What will the final volume of the sample be if the temperature
is held constant?
13. A gas has a volume of 1.75 L at -23oC and 150.0 kPa. At what temperature would
the gas occupy 1.30 L at 210.0 kPa?
14. A gas at 7.75 x 104 Pa and 17oC occupies a volume of 850.0 cm3. At what
temperature, in degrees Celsius, would the gas occupy 720.0 cm3 at 8.10 x 104 Pa?
15. The normal respiratory rate for a human being is 15.0 breaths per minute. The
average volume of air for each breath is 505 cm3 at 20.0oC and 9.95 x 104 Pa. What
is the volume of air at STP (0oC and 1 atm) that an individual breathes in one day?
