Exploring Intermolecular and Intramolecular Forces
Topics: Temperature, Attractive Forces, and Phase Changes
In the context of phase changes, students infer the strength of electrical forces within and between particles. Students conduct an investigation of vapor pressure, comparing the macroscopic, earth’s water cycle, to the microscopic, the intermolecular forces of water and other gases in the atmosphere. Students learn about the heating curve model and the relationship between temperature and kinetic energy.
