States of Matter - Interactive Simulation
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.
