What Is the Kinetic Molecular Theory? Why Gases Fill Any Container

Continuous random motion, elastic collisions, and negligible attraction allow ideal-gas particles to spread through the available volume of any container.

Evidence boundary

This explanation uses the ideal-gas kinetic-molecular model. Real gases approach this behavior most closely when molecular volume and intermolecular attractions are relatively unimportant, generally at lower pressures and higher temperatures. The question is qualitative and supplies no numerical gas data.
