The kinetic molecular theory posits that gas particles are in constant random motion and that they occupy a much larger volume than the volume of the particles themselves. Within this framework, it is understood that gas particles experience minimal to negligible intermolecular forces. This lack of attraction allows gas particles to move independently of one another, resulting in properties such as low density and the ability to fill their container.

The theory also notes that because of the significant distance between gas particles, any intermolecular forces present are so weak that they can be considered as nonexistent during most conditions. This characteristic of gases contrasts with liquids and solids, where intermolecular forces are much stronger and lead to more cohesive behavior among particles.
