Please note:

  • Your answers must be submitted in the form of a Microsoft Word document.
  • Include your Penn State Access Account user ID in the name of your file (for example, "module2_abc123.doc").
  • The due date for this assignment will be sent to the class by e-mail in ANGEL.
  • Your grade for the assignment will appear in the drop box approximately one week after the due date.
  • You can access the drop box for this module in ANGEL by clicking on the Lessons tab, and then locating the drop box on the list that appears.

Problem Set

  1. Explain in your own words (no more than a paragraph) why the 2-Phase segment of the P-v isotherm should correspond to one single point in the P-T diagram.
  2. What about the critical point in the P-T diagram? Which P-v isotherm could that correspond to?
  3. Take two different hydrocarbons (say, C1 and C2) and compare their P-T vapor pressure curves. What do you notice? As you saw in the previous module, those P-T curves will be found at different conditions of pressure and temperature. But more than that, what can you comment about the slopes of both curves? Are they different? Why? Speculate.
