Like most substances, bromine exists in one of the three typical phases. Br2 has a normal melting point of 27.2oC and a normal boiling point of 59oC. The triple point for Br2 is 27.3oC and 40 torr, and the critical point is 320oC and 100 atm. Using this information, sketch a phase diagram for bromine indicating the points described above. Based on your phase diagram, order the three phases from least dense to most dense. What is the stable phase of Br2 at room temperature and 1 atm? Under what temperature conditions can liquid bromine never exist? What phase changes occur as the temperature of a sample of bromine at 0.10 atm is increased from 250oC to 200oC?
