1) In class we considered the temperature dependence of chemical potential. Roughly sketch the chemical potential vs. pressure (y vs. x) for water at 100°C from about 1 Pa to 1 MPa. Label the appropriate regions with what phase they contain. What does the slope of these curves correspond to? Hint: It will be useful to look up the appropriate phase diagram for water over this pressure range.

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...
