Copy of Kinetic Molecular Theory Questions (5/28/2026)

Provide an abbreviated list (you don't need to be word-for-word, just capture the gist of each postulate) of the postulates of the kinetic-molecular theory. Assess how good or bad the KMT does with how real gases behave.

Which of the following will have particles moving at O^oC?

Select all of the following with the highest average kinetic energy.

Explain your answer to #4, above.

Using the postulates of the kinetic‑molecular theory, explain why a gas uniformly fills a container of any shape.

Can the speed of a given molecule in a gas double at constant temperature? Explain your answer.

Describe what happens to the average kinetic energy of ideal gas molecules when the pressure of the gas is increased by reducing the volume at constant temperature.

Describe what happens to the average kinetic energy of ideal gas molecules when the pressure of the gas is increased by increasing the temperature at constant volume.

Describe what happens to the average kinetic energy of ideal gas molecules when the average speed of the molecules is increased by a factor of 2.

Consider the diagram of a solid, liquid, a gas. It has been stated that gases are compressible but solids and liquids are generally not. Provide an explanation for this.
