A pressure of a gas is due to:
Correct answer: B. Molecular impacts against the walls of vessel
- A. Rapid intermolecular collisions
- B. Molecular impacts against the walls of vessel
- C. Voids between the gas molecules
- D. Ideal behaviour of gases
Explanation
The pressure of a gas is due to collisions of gas molecules against the walls of container.It is a postulate of KMT.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
