1. For example, the Helmholtz free energy may be written: 2. Substituting Q into the statistical definition, the Helmholtz free energy now reads 3. For these studies, Helmholtz free energy is used. 4. As an example of another thermodynamic potential, the Helmholtz free energy is written: 5. The article Helmholtz free energy contained many mistakes for many years, until 2008. 6. :Example 3 Helmholtz free energy , largely rewritten by me is not adequately sourced. 7. Articles like Helmholtz free energy , Fundamental thermodynamic relation were affected and completely rewritten by me. 8. Where A is the Helmholtz free energy , S is the entropy and T is the temperature. 9. The Helmholtz free energy is a useful quantity when studying thermodynamic transformations in which the temperature is held constant. 10. From the fundamental thermodynamic relation, it follows that the differential of the Helmholtz free energy A is given by:
