This document is designed for a junior or senior level course in physical chemistry. In particular the document introduces the techniques for computing the change in enthalpy associated with the temperature change and the expansion of real gases. It uses the imperfection concept. This gives the students a first hand experience with computing thermodynamic properties associated with processes involving real gases. The document shows how to compute the Joule Thomson coefficient and the Joule Thomson inversion temperature for a real gas using the Redlich-Kwong equation. There are seven hands-on exercises for students imbedded in a full text description of the thermodynamic concepts. The connection to refrigeration is made. References are given. The working gas in the document is SO2. Students can adapt the document to other gases or other equations of state for real gases as mastery exercises.
