Quizplus · Accepted Answer

The kinetic molecular theory of gases postulates that gas molecules are in constant motion, the collisions between molecules are elastic, the volumes of molecules are negligible compared to the volume of the container, and the gas molecules are in rapid motion. However, it does not state that at a constant temperature, each molecule has the same kinetic energy. In fact, the kinetic energies of gas molecules follow a distribution, known as the Maxwell-Boltzmann distribution, where some molecules have higher kinetic energy than others.
