Introduction to Chemical Engineering Thermodynamics - Chapter 5: Convenience Functions

In this screen cast I introduce the combined statement of the first and second law, which gives an expression for the internal energy (U) with natural independent variables entropy (S) and volume (V). We then introduce the convenience functions enthalpy (H), Helmholtz free energy (A), and Gibbs free energy (G). Below is a link to the derivation from the end of the screen cast which can also be found in the nice typed notes I provide in class (also provided below). https://drive.google.com/file/d/1Odwgew8prQ5Skh7NtlvDbCoetSYQ4wDk/view?usp=sharing https://drive.google.com/file/d/19cC3q4zkWVZHh5-sOOPZU2h1QuDsl5uT/view?usp=sharing ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Subscribe: https://www.youtube.com/c/AndrewPaluch?sub_confirmation=1
