Water Phase Diagram Kelvin. The reason is that water is an unusual. Area boc represents the solid ice phase which is the thermodynamically most stable state under these conditions.
Data in the table above is given for water steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Y axis pressure in pascals 10 n. The lines represent the combinations of pressures and temperatures at which two phases can exist in equilibrium.
The phase diagram for water is shown in the figure below.
The labels on the graph represent the stable states of a system in equilibrium. The reason is that water is an unusual. The lines represent the combinations of pressures and temperatures at which two phases can exist in equilibrium. Pressure of the equilibrium is given in the second column in kpa.
