What assumptions are made in the Kinetic Theory about an ideal gas? There are no forces of attraction between molecules The molecules are in a state of continuous random motion The size of the molecule is negligible
Correct answer: E. I, II, III
- A. I ONLY
- B. II ONLY
- C. I AND II ONLY
- D. II AND III ONLY
- E. I, II, III
Explanation
According to Kinetic Molecular Theory , there are no attractive forces between the molecules of a gas because the distance between them is very large. The gaseous molecules are in continuous random, zigzag motion called Brownian motion. Gaseous molecules have negligible sizes as compared to liquids and solids. As all the three statements are true hence , option E is the correct answer.

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.
