4.4 The Molecular Dynamics Simulator

Chemical Concept Demonstrated: The kinetic molecular theory


  • Watch the molecular dynamics simulator and the metal spheres inside. Increasing the voltage is like increasing the temperature in a container.
  • Study what happens to the frequency of colllisions with the wall as the "temperature" increases and when more spheres are added.


    As the "temperature" increases, the spheres hit the edges more frequently.  When more spheres are added, the interparticle collisions are more frequent.  The larger particles that are added move more slowly than their smaller counterparts.


    The kinetic molecular theory is demonstrated by use of the simulator.  The following aspects of the theory can be noted:
