04 (5 maris) Schematic temperature dependence of the chemical potential of the solid, liquid, and gas phases of water at a constant pressure is shown below. T (a) Label the phases, and boiling and freezing temperatures. (6) What is the effect of deceasing pressure on bailing and freezing temperatures? Show on graph. (c) Based on bl, what will be the son of the slope of the solid-liquid phase boundary of water? (d) Show on the sketch below why liquid water is the most stabie phase at room temperature
