The defined states correspond to regions on the pressure-volume diagram of the substance, the initial state lying to the lower volume side of a boundary defined by the branch of the critical isentrope lying to the greater pressure side of the critical point, and by the stability limit of the substance. The final state lies to the greater volume side of this boundary.Other References
