Abstract: In a previous letter and other papers, we have interpreted the supercritical region of fluids as being parted into a gas-like and a liquid-like regimes. The boundary between these two distinct regions of the P-T phase diagram of substances is represented by the Widom line, extending the subcritical liquid-gas 1st order transition line above the critical point. Out authors have been commenting on our interpretation, claiming that the two regions are parted by the so called Frenkel line, which does not reconnect to the subcritical liquid-gas phase boundary. In this work, we show on a solid theoretical basis that the Frenkel line is incorrect and that indeed the Widom line is the relevant boundary between to two supercritical regimes.
