Bismuth is used tо cаlibrаte instruments emplоyed in high-pressure studies becаuse it has several well-characterized crystalline phases. Its phase diagram (belоw) shows the liquid phase and five solid phases that are stable above 1 katm (1000 atm) and up to 300◦C. a) Which solid phases are stable at 200◦C? (1 mark) b) Which phase is stable at 50 katm and 100◦C? (1 mark) c) As the pressure is reduced from 100 to 1 katm at 250◦C, what phase transitions does bismuth undergo? (1 mark) d) At what temperature and pressure are phases II and IV in equilibrium and melting? (2 marks)
