90. Like most substances, bromine exists in one of the three typ- ical phases. Br, has a normal melting point of –7.2°C and a normal boiling point of 59°C. The triple point for Br2 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 tem- perature 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 -50°C to 200°C?

Transcribed Image Text:90. Like most substances, bromine exists in one of the three typ-
ical 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
T 7.3°C and 40 torr, and the critical point is 320°C and
100 atm. Using this information, sketch a phase diagram for
tom
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 tem-
fom
perature 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 -50°C to 200°C?
