Phase Diagrams: Pure Substances

This lecture covers the concept of phase diagrams for pure substances, focusing on the p-v-T diagram. It explains the significance of the critical point, triple line, and saturation state. Examples are provided to illustrate the use of phase diagrams in determining states and properties of substances. The lecture also discusses the projection of phase diagrams onto different planes and the importance of property tables in determining specific volumes, internal energies, enthalpies, and entropies for various states.
