Question

Which of the following statements is not part of the kinetic molecular theory?

• A. The average kinetic energy of gas molecules is proportional to temperature
• B. Attractive and repulsive forces are present between gas molecules
• C. Collisions between gas molecules are perfectly elastic
• D. Gas molecules travel in a continuous. random motion
• E. The volume that gas molecules occupy is minimal compared to the volume in which the gas is contained

Answer 1

The correct option is B Attractive and repulsive forces are present between gas molecules

The following statement is not part of the kinetic molecular theory :

• Attractive and repulsive forces are present between gas molecule. According to the kinetic molecular theory, there is no attractive (or repulsive) force between the molecules, as they move independent of each other.
