Which of the following does Kinetic Molecular Theory NOT predict?

•   Gases are compressible.

•   Gases take the shape and volume of their container.

•   Gases are able to easily conduct electricity.

•   Gases have low densities compared to liquids and solids.

When you have multiple kinds of gases in a sample, KMT does not hold and the particles begin to interact.

• True

• False

When multiple gases are in a container, the sum of the partial pressures is greater than that of the total pressure of the gas.

• True

• False

Under which of the following conditions does the Ideal Gas Law (and therefore KMT) fail?

• Low pressure and Low Pressure

• low pressure & high temperatures

•   High pressures & low temperatures

• High Temperatures & High pressure

If you increase the volume of a gas, how does this affect the pressure? (Assume all other properties are held constant)

• It increases

• It decreases

If you increase the volume of a gas, how does this affect the temperature? (Assume all other properties are held constant)

• Decreases

• Increases

If you increase the number of moles of a gas, how does this affect the volume? (Assume all other properties are held constant)

• Increases

• Decreases

If you increase the temperature of a gas, how does this affect the pressure? (Assume all other properties are held constant)

• Increases

• Decreases

Which of the following statements is a part of the kinetic Molecular Theory of Gases? 

•   Gases are mostly empty space and do not interact with one another and no repulsion

•   Gases are constantly moving around and occupying all the volume they are given

•   The average kinetic energy of the particles is proportional to the temperature

•   Collisions of gas particles with themselves and the container are considered perfectly elastic

• all of the above

The pressure of a gas is a measure of the random motion of particles in the gas.

• True

• False
