Abstract

The Van der Waals equation of state for one mole of an imperfect fluid reads The critical constants are predicted to be The Van der Waals equation can be recast in the form of a universal reduced equation of state in terms of reduced variables Isotherms where is constant can be plotted on the versus diagram using the slider for values of between 080 and 120 The critical isothermis shown in
