Which of the following is an assumption of the kinetic-molecular theory of gases?

• Gas particles stick together after collisions

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

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

According to the kinetic molecular theory, which statement best describes the motion of gas particles?

• Gas particles are stationary.

• Gas particles are only in motion when a gas is heated.

• Gas particles are in continuous, random motion.

• Gas particles move together in the same direction.

According to the kinetic molecular theory of gases, the pressure of the gas is due entirely to the ―

• size of the gas particles compared to the size of its container

• mass of the gas particles compared to the size of its container

• force of the collisions of the gas particles with the walls of the container

• moles of gas particles within the walls of the container

Which statement below does not describe the behavior of an ideal gas according to the kinetic molecular theory?

• The particles are in constant random motion.

• Collisions between the particles are completely elastic.

• There are intermolecular forces of attraction and repulsion between the particles.

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