Chemistry Quiz 11 (Ch 11)

What causes a gas to exert pressure?

• collisions

• density

• temperature

• elevation

The pressure exerted by a gas does not depend on

• temperature.

• volume.

• number of moles present.

• the identity of the gas.

For a fixed amount of gas at a constant temperature, the volume increases as the pressure

• remains steady.

• increases.

• decreases.

• fluctuates.

The direct relationship between temperature and volume is known as

• Kelvin’s law.

• Charles’s law.

• Boyle’s law.

• Avogadro’s law.

Gay-Lussac’s law shows a direct relationship between temperature and

• volume.

• composition.

• density.

• pressure.

At the same temperature and pressure, balloons of equal volume always contain

• equal masses of gas.

• equal numbers of molecules.

• equal densities of gas.

• equal number of atoms.

Which law implies that the volume of a gas is directly proportional to the number of moles of the gas?

• Charles’s

• Boyle’s

• Avogadro’s

• Gay-Lussac’s

The ideal gas law states the relationship among

• pressure, volume, temperature, the gas constant, and number of moles.

• pressure, volume, and temperature only.

• the gas constant and pressure only.

• the gas constant and volume only.

Gas molecules will diffuse faster if the

• temperature decreases.

• temperature increases.

• pressure decreases.

• volume increases.

The average kinetic energy of the particles in any gas depends only on the

• volume of the gas.

• pressure of the gas.

• temperature of the gas.

• number of moles of the gas.
