Gas Laws

A gas cylinder contains 2.0 mol of gas X and 6.0 mol of gas Y at a total pressure of 2.1 atm. What is the partial pressure of gas Y?

1.6 atm

Which law is described by saying that doubling the absolute temperature will double the pressure of a sample of gas in a rigid container?

Boyle's law

Which equation is derived from the combined gas law?

C.

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions?

Charles's law

Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions?

Gay-Lussac's law

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of the gas?

It increases by a factor of four.

A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen, and nitrogen. Which term most likely describes what she is measuring?

partial pressure

The gas in the piston is being heated, and the piston has moved upward. The observation will be summarized in a row of the incomplete table below.

temperature and volume

If two gases are present in a container, the total pressure in the container is equal to

the sum of the pressures that are exerted by each of the two gases.

Five gases combined in a gas cylinder have the following partial pressures: 3.00 atm (N2), 1.80 atm (O2), 0.29 atm (Ar), 0.18 atm (He), and 0.10 atm (H). What is the total pressure that is exerted by the gases?

5.37 atm
