Solid, Liquid or Gas PowerPoint

SOLVED: In the water phase diagram, the solid-liquid boundary has a negative slope, whereas the solid-gas and liquid-gas boundaries have positive slopes. This is because:I. The enthalpy change of sublimation (∆Hsub) is always greater than the enthalpy change of melting (∆Hfus) since enthalpy is a state function (∆Hsub = ∆Hfus ∆Hvap).II. According to Le Chatelier's principle, the higher the pressure on water at low temperatures, the greater the volume, and therefore more solid will be
