Description

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

Sample Learning Goals

  • Describe a molecular model for solids, liquids, and gases.
  • Extend this model to phase changes.
  • Describe how heating or cooling changes the behavior of the molecules.
  • Describe how changing the volume can affect temperature, pressure, and state.
  • Relate a pressure-temperature diagram to the behavior of molecules.
  • Interpret graphs of interatomic potential.
  • Describe how forces on atoms relate to the interaction potential.
  • Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.
