Two Maxwell-Boltzmann distribution curves are shown in the graph above. The curves depict the probability distributions for two types of gases that are held in a single container. One of the gases is made of heavy atoms and one is made of lighter atoms. The atoms are allowed to mix and the container is left alone for a long time. The curves shown in the graph were taken after the atoms had mixed together.
