Which of the following is true about the kinetic molecular theory?

(a) the volume of a gas particle is considered to be small – about 0.10 ml.
(b) pressure is due to the collisions of the gas particles with the walls of the container.
(c) gas particles repel each other, but do not attract one another.
(d) adding an ideal gas to a closed container will cause an increase in temperature.
(e) at least two of the above statements are correct.

(B) Pressure is due to the collisions of the gas particles with the walls of the container.

Option B helps to explain the factor behind gas collision under high pressure.

Explanation: Kinetic molecular theory explains the behaviour and movement of gas particles when they are in motion. It states that gas particles are always in continuous motion and are perfectly elastic in nature.

Kinetic molecular theory can be explained using both Boyle's law and Charles's law.

•Few Assumptions of Kinetic Molecular Theory.

1. Gas particles are always in motion and they collide with the walls of their container.

2. The space occupied by a gas particles is negligible in comparison to the volume of the gas

the answer is d.) potassium
