Question

Which of the following is NOT a part of the Kinetic Molecular Theory?


The particles of an ideal gas exert strong attractive forces on each other and on their surroundings.

The volume occupied by the individual particles of a gas is negligible compared to the volume of the gas itself.

Gas particles are in a constant state of random motion and move in straight lines until they collide with another body.

The collisions exhibited by gas particles are completely elastic; when two molecules collide, total kinetic energy is conserved.

Answer 1

The particles of an ideal gas exert strong attractive forces on each other and on their surroundings is NOT a part of the Kinetic Molecular Theory

Explanation:

The Kinetic Molecular Theory makes assumptions;

1. That the molecules of the gas have negligible volume compared to the volume of the gas itself (therefore even the intermolecular forces between the gas molecules will be negligible)
2. Gas particles are in a constant state of random motion and move in straight lines until they collide with another body.
3. The collisions exhibited by gas particles are completely elastic; when two molecules collide, total kinetic energy is conserved.
4. The gas’ absolute temperature is the sole parameter that determines the average kinetic energy of the gas molecules
