Generalized procedures for estimating vapor pressures critical constants and heats of vaporization have been elaborated. New methods are presented for dealing with equilibrium problems in extraction adsorption dissolution and crystallization. The construction and use of enthalpy-concentration charts have been extended to complex systems. The treatment of material balances has been elaborated to include the effects of recycling by-passing changes of inventory and accumulation of inerts. In the second part the fundamental principles of thermodynamics are presented with particular attention to generalized methods. . The applications of these principles to problems in the compression and expansion of fluids power generation and refrigeration are discussed. However it is not attempted to treat the mechanical or equipment problems of such operations.</span><span style="color: rgb(33, 37, 41); font-family: system-ui, -apple-system, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans", "Liberation Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; letter-spacing: 0.7px; text-align: justify;"><br></span><br></p>
