Worksheet  on Boyle’s Law

1) At constant temperature, what happens to the pressure when the volume is doubled?

a)      It is halved                    b) It is doubled                  c) It remains the same

    d) It is quadrupled            e) It cannot be predicted

2) To use Boyle's Law, which of the following needs to remain constant?

    a) Temperature and number of moles of a gas

    b) Temperature and pressure

    c) Pressure and number of moles of a gas

    d) Pressure and volume

    e) Temperature and volume

3) A sample of hydrogen has a volume of 25 L under a pressure of 5 atm. What will the pressure of this gas be if the volume were decreased to 5 L?

4) Given a container of nitrogen gas with an initial volume of 10 L and pressure of 28 Pa,
calculate the volume if the pressure becomes 1 Pa. The temperature and amount of mass stay constant.

5) What is a mathematical expression of Boyle's Law?
a) P₁V₂=P₂V₁               b) P₁/V₁=P₁/V₁                 c) P₁V₁=P₂V₂                    d) P₁V₂=P₂/V₁               

e) None of the above

6) Consider an inflated balloon. The force holding the walls of an inflated balloon open is the:

a) Repulsive force between the molecules and the wall of the balloon.

b) Static forces pushing the walls of the balloon apart.

c) Force of the molecules hitting the inside of the walls of the balloon.

d) Force of gravity.

7) According to Boyle's Law:

a) The volume of gas in a closed container does not change when pressure is changed.

b) The change in the volume of a gas in a closed container is inversely proportional to changes in pressure.

c) Increasing the pressure on a volume of gas wall cause the volume to increase.

d) The change in the volume of a gas in a closed container is directly proportional to changes in pressure.
