Allows you to see a graphical representation of molecular motion of gazes and how changing pressure, temperature, volume, and moles can affect that motion. The automatic portion of the program takes you through a step by step process where parameters are changed and the effect on the system can be visualized as the changes occur. As temperature is changed, the ideal gaz law can be examined as well as the Maxwell-Boltzmann distribution of molecular kinetic energy.The manual portion of the program lets you vary pressure, moles, volume, and temperature and see the effects on the system.
