(a) Sketch a Pressure-Temperature phase diagram for a pure substance X where liquid X is less dense than solid X. Insert an isobar at 1 atm and an isotherm at 300 K. Clearly label all physical states, triple point, critical temperature and any normal transition temperatures.
The given figure shows the pressure-temperature phase diagram for H2O. Apply the Gibbs phase rule at points A,B, and C, and specify the number of degrees of freedom at each of the points, that is, the number of externally controllable variables that need to be specified to completely define the system.
