There are two essential elements: the state of the material, in other words, its physical characteristics such as temperature or specific volume and the processes that the materials that make up the system may undergo as energy is exchanged. There must be more to the properties of gases than can be described through the ideal gas law. For real fluids, the enthalpy can also be a function of pressure. Under these circumstances, we need a new method of evaluating the thermodynamic properties of the fluid. For liquid–vapor equilibrium, we used Raoult's law to estimate the amount of the liquid that could transfer into the vapor phase. Solid liquid equilibrium is observed when a solid is dissolved into a liquid solvent, such as a salt in water. In such cases in the inorganic chemical industry, crystallization is employed as a separation process, particularly where salts are recovered from aqueous media.
