1. In Figure 9.38 is shown the pressure- temperature phase diagram for H2O. Apply the Gibbs phase rule at points AB, and C; that is, specify the number of degrees of freedom at each of the points-that is, the number of ex- ternally controllable variables that need be specified to completely define the system.
