Answer: (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 kinetic molecular theory postulates the pressure of the gas has been the result of the collision of gas particles with container walls. Thus, option B is correct.
The kinetic molecular theory has been used for the determination of the motion of the gaseous particles. The theory has been assuming the gas particles to be in continuous motion. The gas particles with motion have been colliding with the container walls as well.
The collision between the gas particles and the container's wall has been responsible for the pressure of the particular gas. Thus, option B is correct.
