Discuss the phase changes that occur in the liquid solid and liquid vapor boundary. Describe how the locations of phase boundaries are obtained. Discuss any assumptions used in the Clasius Clapeyron equation. For a substance such as carbon dioxide or water, calculate and graph the phase boundaries in the solid vapor, solid liquid, and liquid vapor regions. List the data you will need to calculate the pressure temperature composition line for each type of boundary.
