= Thermodynamic free energy
{wiki=Thermodynamic_free_energy}
Thermodynamic free energy is a concept in thermodynamics that quantifies the amount of work that can be extracted from a system at constant temperature and pressure. It provides a useful measure to determine the spontaneity of processes and the equilibrium state of systems. There are two commonly used forms of free energy: 1. **Gibbs Free Energy (G)**: This is used for systems at constant temperature (T) and pressure (P).
