Chemistry Chapter 14 Review

Which law/rule states that at a constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases?

• Combined Gas Law

• Dalton's Law of Partial Pressure

• Boyle's Law

• Ideal Gas Law

The volume of a fixed mass of gas is directly proportional to the temperature if the pressure is kept constant relates to

• Charles' Law

• Boyle's Law

• Dalton's Law

• Ideal Gas Law

As the temperature of a fixed volume of gas increases, the pressure will

• vary inversely

• decrease

• be unchanged

• increase

The phrase “as gas tends to move to an area of lower concentration until the concentration is uniform throughout” reflects the concept of

• partial pressures

• osmosis

• diffusion

• the ideal gas constant

Increasing the volume of a given amount of gas at a constant temperature causes the pressure to decrease because

• the molecules are striking a larger area with the same force

• there are fewer molecules

• the molecules are moving more slowly

• there are more molecules

The volume of a gas is doubled while the temperature is held constant. The pressure of the gas

• remains unchanged

• is reduced by 1/2

• is doubled

• depends on the type of gas

The escape of gas from a tiny hole in a container is

• effusion

• diffusion

• compressibility

• partial pressures

A measure of how much the volume of matter decreases under pressure

• compressability

• effusion

• diffusion

• partial pressures

Which of the following would double the pressure on a contained gas at a constant temperature?

• doubling the volume of the container

• halving the number of particles in the container

• doubling the number of particles in the container

• none of the above

At a constant pressure, the volume of a fixed mass of gas and its Kelvin temperature are said to be

• directly related

• inversely related

• constant

• unrelated
