4) Given the phase diagram, answer the questions below. You do not have to make a calculation to answer the questions. Think about how pressure and temperature may vary independently of each other at different locations on the diagram (indicated in the questions). a. If you plot a pressure and temperature combination that falls on the line between Kyanite and Sillimanite, what are the degrees of freedom? b. What if you chose a pressure and temperature combination that plots anywhere in the Andalusite field. How many degrees of freedom exist here? c. What does it mean physically for a pressure and temperature combination that plots in the andalusite field? d. How many degrees of freedom are at the triple point?
