An earth battery is a pair of electrodes made of two dissimilar metals, ... and energy is imparted to the medium in such manner that "free electrons" in the medium ...
The minimization of the Gibbs free energy is a form of the principle of minimum energy (minimum 'free' energy or exergy), which follows from the entropy maximization principle for closed systems. Moreover, the Gibbs free energy equation, in modified form, can be used for open systems , including situations where chemical potential terms are ...
Free energy suppression (or new energy suppression) is a conspiracy theory that technologically viable, pollution-free, no-cost energy sources are being suppressed by governments, corporations, or advocacy groups.
Free-energy relationship, a relationship in physical organic chemistry; Principle of minimum energy, a thermodynamic formulation based on the second law; Thermodynamic free energy, the energy in a physical system that can be converted to do work, including: Gibbs free energy; Landau free energy (also known as grand potential) Helmholtz free energy
The free energy principle is a mathematical principle of information physics: much like the principle of maximum entropy or the principle of least action, it is true on mathematical grounds. To attempt to falsify the free energy principle is a category mistake, akin to trying to falsify calculus by making empirical observations. (One cannot ...
Free energy - energy state function; Geothermal energy – thermal energy extracted from the Earth's crust; Gravitational energy – energy from gravitational fields; Ionization energy – energy that binds an electron to its atom or molecule; Kinetic energy – (≥0), energy of the motion of a body; Magnetic energy – energy from magnetic fields
The heat death of the universe (also known as the Big Chill or Big Freeze) [1] [2] is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy.
The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, in their standard states (the most stable form of the element at 25 °C and 100 kPa).
