- 8.1: Fundamental Equation of Thermodynamics
- Let’s summarize some of the results from the first and second law of thermodynamics that we have seen so far.
- 8.2: Thermodynamic Potentials
- Starting from the fundamental equation, we can define new thermodynamic state functions that are more convenient to use under certain specific conditions. The new functions are determined by using a mathematical procedure called the Legendre transformation.
- 8.3: Free Energies
- he Legendre transformation procedure translates all information contained in the original function to the new one. Therefore, H(S,P,{ni}) , A(T,V,{ni}) , and G(T,P,{ni}) all contain the same information that is in U(S,V,{ni}) .
- 8.4: Maxwell Relations
- Let’s consider the fundamental equations for the thermodynamic potentials that we have derived in section 8.1.
