As with any scientific theory, it is not possible to prove that the kinetic molecular theory is the correct way of explaining and understanding the properties of gases on a molecular level. However, the kinetic molecular theory is consistent with experimental measurements. Experiments using this molecular-level model have shown that this theory has significant explanatory and predictive power for the majority of gases at reasonably low pressures and high temperatures.

The kinetic molecular theory is a remarkable example of how a simple molecular level model can explain as well as predict a variety of physical phenomena.
