States of Matter
Description
  • 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.

States of Matter: Basics
Description
  • Describe characteristics of three states of matter: solid, liquid and gas.
  • Predict how varying the temperature or pressure changes the behavior of particles.
  • Compare particles in the three different phases.
  • Explain freezing and melting with molecular level detail.
  • Recognize that different substances have different properties, including melting, freezing and boiling temperatures.
