What is Free Energy? - Stanford University

WebThe free energy is a thermodynamic state function, like the internal energy, enthalpy, and entropy . The free energy is the portion of any first-law energy that is available to perform thermodynamic work at constant temperature, i.e., work mediated by thermal energy. Free energy is subject to irreversible loss in the course of such work. [1] WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ... WebCategory. v. In thermodynamics, the Helmholtz free energy (or Helmholtz energy) is a thermodynamic potential that measures the useful work obtainable from a closed thermodynamic system at a constant temperature ( isothermal ). The change in the Helmholtz energy during a process is equal to the maximum amount of work that the … dm with pdr
