energy transfer
71Earth's energy budget — [ thumb|right|250px|A schematic representation of the energy exchanges between the EarthEarth s atmosphere, and outer space. Note that the total energy entering each level is equal to the energy leaving that level as should be expected for a… …
72heat transfer — ▪ physics any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation (qq.v.), and… …
73Electron transfer — (ET) is the process by which an electron moves from one atom or molecule to another atom or molecule. ET is a mechanistic description of the thermodynamic concept of redox, wherein the oxidation states of both reaction partners change. Numerous… …
74Flywheel energy storage — NASA G2 flywheel Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel s rotational speed… …
75Directed-energy weapon — This article is about practical experiments with energy weapons. For fictional uses, see raygun. Humvee with Active Denial System mounted A directed energy weapon (DEW) emits energy in an aimed direction without the means of a projectile. It… …
76SSME energy and power relationships — The Space Shuttle main engines are rockets that use liquid hydrogen and oxygen propellants. The ejection of propellants represents a “flow” of momentum; as a consequence of the law of conservation of momentum an equal and opposite force and… …
77Dexter electron transfer — is a quenching mechanism in which an excited electron state transfers from one molecule (the donor) to a second (the acceptor). This requires a wavefunction overlap between the donor and acceptor, so can only occur at short distances; typically… …
78Vibrational energy relaxation — Vibrational energy relaxation, or vibrational population relaxation, is a process in which the population distribution of molecules in vibrationally quantum states of high energy level caused by an external perturbation returns to the Maxwell… …
