Make a sketch of the Gibbs free energy, G, versus temperature, T, for a single component system as the temperature increases at a fixed pressure, P.
Indicate the temperatures where the pure substance changes from liquid to solid, and from solid to gas, and comment on the slopes of the plot of G versus T.
