Phase diagram | physics | Britannica Phase diagram, graph showing the limiting conditions for solid, liquid, and gaseous phases of a single substance or of a mixture of substances while undergoing changes in pressure and temperature or in some other combination of variables, such as solubility and temperature. The Figure shows a Phase diagrams PetroWiki A phase is the portion of a system that is homogeneous, is bounded by a surface, and is physically seperable from other phases. Equilibrium phase diagrams offer convenient representations of the ranges of temperature, pressure, and composition within which various combinations of phases coexist. Critical point (thermodynamics) The liquid–liquid critical point of a solution, which occurs at the critical solution temperature, occurs at the limit of the two phase region of the phase diagram. In other words, it is the point at which an infinitesimal change in some thermodynamic variable (such as temperature or pressure) will lead to separation of the mixture into two distinct liquid phases, as shown in the polymer–solvent phase diagram to the right. RESERVOIR FLUID OIL RESERVOIRS AND PHASE DIAGRAM To fully understand the significance of the pressure temperature diagram, it is necessary to identify and define the following key points on these diagrams: Cricondentherm (Tct):The Cricondentherm is defined as the maximum temperature above which. PHASE DIAGRAM. liquid cannot be formed regardless of pressure (point E). Water phase diagram London South Bank University e The phase diagram for heavy water (D 2 O) differs little from the diagram for H 2 O given the scales used in the diagram. A more accurate representation would be by shifting the temperature scale by about 3.6 K as most of the triple points for D 2 O are 3 4 K warmer than those for H 2 O (see above ). Phase diagram Physics The simplest phase diagrams are pressure–temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature .
