We can use the phase diagram to answer the given questions.
Recall that a phase diagram shows the transition of matter between solid, liquid, and gas phases as temperature and pressure changes.
In a phase diagram, the different phases can be identified by their location:
• Solid: can be found at high pressure and low temperature
• Liquid: can be found between the solid and gas regions
• Gas: can be found at low pressure and high temperature
The given phase diagram is:
Answer the following questions based on the following phase diagram given below.
a. At what temperature can we no longer tell the difference between the liquid and the gas? _____________
b. Which point represents an equilibrium between the solid, liquid, and gas phase? _____________
c. Which line segment represents an equilibrium between fusion and freezing? _____________
d. Which line segment represents an equilibrium between sublimation and deposition? _____________
e. Which line segment represents an equilibrium between condensation and vaporization? _____________
f. What is the normal freezing point of this unknown substance? _____________
g. What is the normal boiling point of this unknown substance? _____________
