Which of the following is an assumption of the kinetic model of an ideal gas?
Correct answer: B. Collision between particles are elastic
- A. Gas is at high pressure
- B. Collision between particles are elastic
- C. There are weak forces of attraction between particles in gas
- D. Total energy of particles is proportional to the temperature
Explanation
The five main postulates of the KMT are as follows: (1) The particles in a gas are in constant, random motion. (2) The combined volume of the particles is negligible. (3) The particles exert no forces on one another. (4) Any collisions between the particles are completely elastic. (5) The average kinetic energy of the particles is proportional to the temperature in kelvin.

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.
