Example #1
Copy the example AND the steps necessary to solve the problem:
Now complete the following problems by applying Boyle’s Law:
1. Oftentimes while flying, airplane passengers experience discomfort inside their ears if the cabin undergoes
a drop in air pressure.
a. Draw a picture of the inner ear with gas particles before the drop in air pressure and after the drop
in air pressure.
b. Using Boyle’s Law, explain why airplane passengers experience discomfort if the cabin undergoes a
drop in air pressure.
2. A gas with a volume of 4.00 L at a pressure of 2.05 atm is allowed to expand to a volume of 12.0 L. What is
the pressure in the container if the temperature remains constant?
a. Will the pressure in the container increase, decrease, or stay the same?
b. Draw a picture of the gas particles to explain your thinking.
c. Calculate the new pressure. Show your work.
3. The pressure of 2.50 L of N2O changes from 1.05 atm to 4.05 atm. If the temperature does not change,
what will the new volume be? Show your work.
a. What the volume increase, decrease, or stay the same?
b. Draw a picture of the gas particles to explain your thinking.
c. Calculate the new volume. Show your work.
4. 600.0 mL of a gas is at a pressure of 8.00 atm. What is the volume of the gas at 2.00 atm? Show your work.
5. A sample of gas has a volume of 12.0 L and a pressure of 1.00 atm. If the pressure of gas is increased to
2.00 atm, what is the new volume of the gas? Show your work.
6. If a gas at 25.0°C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of
2.50 atm, assuming the temperature does not change? Show your work.
7. If the pressure on a gas is decreased by one-half, how will the volume change? Show your work.
