“…This ratio represents the critical compressibility factor which measures the behaviour of the ideal fluid and that is perfectly matched with that of the VdW gas/fluids model and known as the universal number and modelled for all fluids [14]. Meanwhile, for the VdW fluid, one can construct a universal dimensionless quantity P c V c T c by employing the essential thermodynamic quantities, with V c being the critical specific volume [18,74].…”

“…( 41), one can notice that if V and S are constants then isochoric processes are additionally adiabatic for dynamic phantom AdS BH due to the connection between volume and entropy [18]. Secondly, at constant pressure Spe- cific heat [14] can be written as, Eq. ( 42),…”

In this paper, we discuss the thermodynamic phase-transition, thermal stability and criticality of dynamic phantom AdS black hole (BH) in the presence of electric charge e and magnetic charge g. To accomplish this, we construct the specific heat and other important thermodynamical parameters which help us to investigate the stability and criticality. The thermodynamical properties of dynamic phantom AdS BH are examined by utilizing the specific heat $$(C_P)$$ ( C P ) , volume expansivity $$(\beta )$$ ( β ) , isothermal compressibility $$(\kappa )$$ ( κ ) , Temperature vs Entropy (T–S), Pressure vs Volume (P–V) and Gibbs free energy G, graphically. Specific heat against entropy describes the divergency behaviour, which produces the second-order phase transition. We also obtain isenthalpic curves for both systems in the T–P plane and determine the cooling and heating regions by utilizing Joule–Thomson expansion. Moreover, we discuss the behaviour of (P–V) isotherm that is equal to the liquid/gas transition of the Van-Der Waals fluid is exactly matched to 3/8 also known as a universal number. Furthermore, we investigate Swallow-tail behaviour and also discuss the stability and instability of the small black hole (SBH), Intermediate black hole (IBH) and large black hole (LBH).
