Isotherms of real gas Dark blue curves – isotherms below the critical temperature. Green sections – metastable states. The section to the left of point F – normal liquid. Point F – boiling point. Line FG – equilibrium of liquid and gaseous phases. Section FA – superheated liquid. Section F′A – stretched liquid (p<0). Section AC – analytic continuation of isotherm, physically impossible. Section CG – supercooled vapor. Point G – dew point. The plot to the right of point G – normal gas. Areas FAB and GCB are equal. Red curve – Critical isotherm. Point K – critical point. Light blue curves – supercritical isotherms
