3. Intermolecular Forces The interplay of attractive and repulsive forces between gas particles dictates macroscopic particle behavior

4. Intermolecular Forces There is no ‘wet lab’ that allows students to observe the effect of intermolecular forces on particles. Therefore teachers introduce intermolecular forces by using direct instruction supplemented with charts and graphs.

5. Intermolecular Forces Simulab 12 provides a hands on activity that allows students to see the interplay of intermolecular forces, particle behavior and energy changes as a function of varying particle distance. The optional extension allows students to explore the effects of changing system temperature.
