Free energy definition chemistry
WebHelmholtz free energy is a concept in thermodynamics where the work of a closed system with constant temperature and volume is measured using thermodynamic potential. It may be described as the following equation: F = U -TS. Where, F = Helmholtz free energy in Joules. U = Internal energy of the system in Joules. Webenergy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.

Webfree energy: [noun] the part of the energy of a portion of matter that may be changed without change of volume : internal thermodynamic potential. WebSurface Energy. Surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created. It is also called surface free energy or interfacial free energy. In simple language, surface energy can be defined as the work per unit area done by the force that creates the new surface.
