Unformatted text preview: 1. Our interest in the fundamental property relations is understanding how we can calculate U, H, S and other state properties from P and T. 2. Much of chapter 6 involves “clever math.” Our emphasis is on using the results of “clever math” rather than on being able to reproduce all of the different expressions in Ch. 6. 3. Gibbs energy is considered a “generating function.” One of our goals as we go through Ch. 6 is to understand what this means. 4. For a truly incompressible fluid, we can analytically show that C P = C V . Key Skills 1. Ability to follow derivation of different fundamental property relations. 2. Ability to utilize physical property measurement data in the fashion of Example 6.1....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
