• Use a ruler and protractor accurately
• Understand the SI system of measurement
• Convert between different units

• 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.

• 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.
