Supercritical water: percolation transitions and a colloidal mesophase

TL;DR

This paper revises the phase diagram of water, revealing three distinct fluid phases with no direct liquid-gas transition or critical point, and introduces a symmetry in the thermodynamic properties of steam and water.

Contribution

It presents a new phase diagram for water that challenges traditional views and introduces a thermodynamic rigidity function highlighting symmetry between steam and water.

Findings

Three distinct fluid phases identified in water.

No continuous transition or critical point between liquid and gas.

Symmetry observed in thermodynamic properties of steam and water.

Abstract

A revised phase diagram for water shows three distinct fluid phases. There is no continuity of liquid and gas and no critical point on Gibbs density surface. A liquid state, water, spans all temperatures. A thermodynamic rigidity function, which distinguishes gas and 'liquid, shows a remarkable symmetry between complimentary corresponding states of steam and water.
