The main purpose for the development of the EOS approach was for generating of data which included volumetric, thermo physical data, and to help perform vapor/liquid equilibrium calculations.

The quality is zero for the saturated liquid and one for the saturated vapor (0 x 1). The average specific volume at any state 3 is given in terms of the quality as follows. Consider a mixture of saturated liquid and saturated vapor. The liquid has a mass mf and occupies a volume Vf. The vapor has a mass mg and occupies a volume Vg. We note
vapor, or water to ice, for example). Many thermodynamic devices rely on these phase changes (liquid-vapor power cycles are used in many power generation schemes, for example). You will learn more about these in 16.050. In this course we will deal only with single-phase thermodynamic systems. Increasing pressure

Vapor adsorbs on a solid surface is a spontaneous process - overall free energy change( G) : negative degree of freedom ( S) : decrease, negative ΔGS For G to be negative, H should be negative, that is, adsorption must be an exothermic process. z The situation may be different in the solid/liquid system.
