Solve each problem. State each gas law and write the formula for each.
1. Some nitrogen gas occupies 3.50 L when its pressure is 210 kPa. How many liters will it occupy when
its pressure is 195 kPa?
2. A gas has a volume of 3.20 L at 312 kPa. What pressure is needed to reduce the volume of the gas to
2.35 L?
3. The Celsius temperature of a 3.00L sample of gas is lowered from 80.0ºC to 30.0ºC. What will be the
resulting volume of this gas?
4. The initial volume of a gas is 250 mL. When the temperature was raised to 25°C, the volume increase
to 400. mL. what was the initial temperature?
5. A gas in a sealed container has a pressure of 125kPa at a temperature of 30.0ºC. If the pressure in the
container is increased to 201kPa, what is the new temperature?
6. The pressure in an automobile tire is 1.88 atm at 25.0ºC. What will be the pressure if the temperature
warms up to 37.0ºC?
7. A helium filled balloon at sea level has a volume of 2.1L at 0.998atm and 36ºC if it is released and
rises to an elevation at which the pressure is 0.90atm and the temperature is 28ºC, what will be the
new volume of the balloon?
8. At 273K and 1.00 atm pressure, a sample of gas occupies 30.0mL. If the temperature is increased to
30.0ºC and the entire gas sample is transferred to a 20.0mL container, what will be the gas pressure
inside the container?
9. What is the pressure of a fixed volume of gas at 30.ºC if it has a pressure of 1.11 atm at 15ºC?
10.Helium gas in a 2.00L cylinder is under 1.12 atm pressure. At 36.5ºC, that same gas sample has a
volume of 2.56 L. What was the initial temperature of the gas in the cylinder?
11. A gas has a volume of 635 L at 88.6 kPa. What will be the volume at standard pressure?
12. A sample of air in a syringe exerts a pressure of 1.02 atm at a temperature of 22ºC. The syringe is
placed in a boiling water bath at 100.ºC. The pressure of air is increased to 1.23atm by pushing the
plunger in, which reduced the volume to 0.224 ml. What was the original volume of the air?
