31. Neutron star relativistic equations of state describe the relation of radius vs . mass for various models. 32. Another definition of a relativistic star is one with the equation of state of a supermassive size. 33. In all, there will be equations for each potential, resulting in a total of equations of state . 34. The classical thermodynamic properties of an ideal gas can be described by two equations of state :. 35. This equation can be shown to be consistent with the usual equations of state employed by thermodynamics. 36. Which only depends upon the equilibrium state potentials like temperature and density ( equation of state ). 37. :: See equation of state # Other equations of state of interest ( stiffened equation of state ). 38. Any equation expliciting one of these transport coefficient in the conservation variables is called an equation of state . 39. For a perfect fluid, another equation of state relating density \ rho and pressure p must be added. 40. :: See equation of state # Other equations of state of interest ( stiffened equation of state ).
