3) Construct a phase diagram for O2 given the following information:
normal boiling point: 90.18K
normal melting point: 54.8K
triple point 54.34K and 2 torr
From your diagram, roughly estimate the vapor pressure of liquid oxygen at -196? C, the lowest temperature easily reached in a lab. Using your diagram, is the density of liquid O2 greater or less than solid O2 and how can you tell?
