版权所有：华东理工大学物理化学教研室 2 The simplest applications of thermodynamics to chemically significant systems are to the discussion of the phase transitions of pure substances. We shall see that a phase diagram is a map of the pressures and temperatures at which each phase of a substance is the most stable. 6. Physical transformation of pure substances

版权所有：华东理工大学物理化学教研室 3 In this chapter, we first describe the interpretation of empirically determined phase diagrams for a selection of materials; then we turn to a consideration of the factors that determine the positions and shapes of the boundaries between the regions on a phase diagram; and finally, we consider the thermodynamic discussion of liquid surfaces, such as surface tension and capillary action. 6.
