Guy-Lussac’s Law (6.5)
6.
The gases in a hair spray can are at a temperature of 27 oC and a pressure of 30 lbs/in2. If the gases in the can reach a pressure of
90 lbs/in2, the can will explode. To what temperature must the gases be raised in order for the can to explode? Assume
constant volume. (630 oC)

Mixed Gas Laws
11) A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.0°C. By noon the temperature has risen to
45.0°C. What is the new volume of the balloon?
12) CaCO3 decomposes at 1200°C to form CO2 gas and CaO. If 25 L of CO2 are collected at 1200°C, what will the volume of this
gas be after it cools to 25°C?
13) There are 135 L of gas in a container at a temperature of 260°C. If the gas was cooled until the volume decreased to 75 L, what
would the temperature of the gas be?
14) 6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume is 3.5 L. What is the new pressure inside the
piston?
15) The initial volume of a gas at a pressure of 3.2 atm is 2.9 L. What will the volume be if the pressure is increased to 4.0 atm?
16) An airtight container with a volume of 4.25 x 10 4L, an internal pressure of 1.00 atm, and an internal temperature of 15.0°C is
washed off the deck of a ship and sinks to a depth where the pressure is 175 atm and the temperature is 3.00°C. What will the
volume of the gas inside be when the container breaks under the pressure at this depth?
17) A weather balloon has a volume of 35 L at sea level (1.0 atm). After the balloon is released it rises to where the air pressure is 0.75
atm. What will the new volume of the weather balloon be?
