5. Below you find a sketch of the p,T-phase diagram of H20, indicating preferred physical states of H20 at different temperatures and pressure. The regions labeled with In, XI, and III, stand for different forms of solid H20. For example, ice Ih is the standard ice (there are more than 12 different forms of solid H2O). Draw two diagrams for the chemical potentials as a function of temperature (from Ti to T2) of each of the phases (there are 5...

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.

The Gibbs function of a thermodynamic system is defined by G H- TS. If the system is consisting of two phases 1 and 2 of a single substance and maintained at a constant temperature and pressure, the equilibriunm condition for the coexistence of these two phases is that the specific Gibbs functions are equal Consider now a first-order phase change between the phase 1 and the phase 2. At the phase boundary, the equilibrium condition for the...
