Help with this problem Like most substances, bromine exists in one of the three typical phases. Br has a normal melting point of 7.2 ° C and a normal boiling point of 59 ° C. The triple point for Br, is -7.3 ° C and 40 torr, and the critical point is 320 ° C 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 Br, at room temperature and I atm? Under what temperature conditions can liquid bromine never exist? What phase changes oCur as the temperature of a sample of bromine att). 10 atm is increased fom 50 Cto 200 C
