Chem 481L Fall 2009 Lab Module #9 Real Substances in the Ideal Limit Thermodynamic Properties Due Date: Noon, Tuesday, November 10 Submit via Blackboard Goal: To explore the physical properties of real gases in the ideal gas limit, specifically constant-volume heat capacity, constant-pressure heat capacity, and the expansion coefficient. Research question: Do real substances, modeled by Virtual Substance, act ideally at low densities? That is, what Cv and Cp are predicted by VS for real substances? What form does the expansion coefficient take when Virtual Substance models a real noble gas at low densities? Reading: Atkins, Physical Chemistry : constant-volume and constant-pressure heat capacities, and expansion coefficient. Introduction: Specific heat: The internal energy of a substance increases as its temperature increases. If the substance is heated in a container of fixed volume, the specific heat capacity at constant volume, C V , can be determined. The specific heat is a measure of how much heat energy a
