• liquid

• solid

According to the kinetic molecular theory, gas particles

• are spaced far apart.
• are constantly moving.
• have mass.
• all choices are correct.

Which of these is explained by the kinetic molecular theory?

• Molecules of gases have a finite volume

• Molecules of gases attract and repel one another.

• Collisions between gas molecules are inelastic

• The kinetic energy of gas molecules depends on temperature.

Which of the following is one of the assumptions of kinetic molecular theory?

• collisions between gas particles and the wall of a container are inelastic

• the temperature of the gas depends on the average potential energy of the gas particles

• gas particles are much larger than the space between them

• the volume of a gas is mostly empty space

According to kinetic molecular theory:

• The motion of the particles in a gas is rapid, constant, and random.

• The motion of the particles in a gas is slow, periodic, and consistent.

According to kinetic molecular theory:

• the average kinetic energy of the particles in a gas depends on the absolute temperature of the gas.

• the average potential energy of the particles in a gas depends on the absolute temperature of the gas.
