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.
