The Gibbs free energy G for a liquid is considered as a function of temperature ( T ) and pressure ( P ) . G is plotted either as a function of temperature at different constant pressures P₁ and P₂ (P₂>P₁ ) or as a function of pressure at different constant temperatures T₁ and T₂ (T₂>T₁ ) . The correct variation of G is best represented as
