A phase diagram is a graphical representation of the physical states of a substance under different pressure and temperature conditions based on experimental data. Generally, pressure-temperature (p-T) diagrams under constant volume (V) are preferred for simplicity and easy understanding. The positions of solid, liquid and gas phases, equilibrium lines between phases, the triple point where these lines intersect (trp) and the critical point (Tcr, Pcr, ρcr) where the liquid-gas equilibrium line ends are located in the p-T diagram of one-component substances. The positions of the triple point and the critical point vary depending on the material taken. In contrast, conventional phase diagrams do not have a position showing the plasma phase, which makes up 95-98% of the universe. In other words, the boundary lines between solid, liquid and gas phases and plasma are not determined. In addition, the ending position of the solid-liquid equilibrium curve, whose beginning is known at the triple point, and the uncertainty of the liquid phase continue.
In this study, the metastable state of benzene at high pressure and temperature was examined and a critical pressure point (pcr) was determined on the melting equilibrium curve. In addition, with the application of the thermodynamic geometry system and the evaluation of the axiomatic method, the melting equilibrium curves of many organic and inorganic substances ending with a critical point has been shown. Location of plasma in single component system p-T phase diagram determined and modeled considering benzene atom.
