On one of these constructs, the barrier between an unstable and a metastable region is given by the spinodal, which always lies inside the binodal.
On one of these constructs, the barrier between an unstable and a metastable region is given by the spinodal, which always lies inside the binodal. Calculating properties at a point on one of these constructs can be done by drawing a tie line and applying the lever rule. The equation "C minus P plus 2" gives the number of degrees of freedom at a point on one of these constructs. Their Txy ("t-x-y") and Pxy ("p-x-y") variants can be used to show the location of (*) azeotropes. Three coexistence curves on the most common type of these constructs meet at the triple point. For 10 points, name these diagrams whose simplest versions typically display the pressure and temperature at which a material exists as a solid, liquid, or gas.
