  2. Endothermic process - Wikipedia

    en.wikipedia.org/wiki/Endothermic_process

    The opposite of an endothermic process is an exothermic process, one that releases or "gives out" energy, usually in the form of heat and sometimes as electrical energy. [1] Thus, endo in endothermic refers to energy or heat going in, and exo in exothermic refers to energy or heat going out. In each term (endothermic and exothermic) the prefix ...

  3. Endothermic gas - Wikipedia

    en.wikipedia.org/wiki/Endothermic_gas

    An endothermic gas generator could be used to supply heat to form an endothermic reaction. [ 1 ] Synthesised in the catalytic retort(s) of endothermic generators, the gas in the endothermic atmosphere is combined with an additive gas including natural gas , propane (C 3 H 8 ) or air and is then used to improve the surface chemistry work ...

  4. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    Thermal decomposition is a chemical reaction where heat is a reactant. Since heat is a reactant, these reactions are endothermic meaning that the reaction requires thermal energy to break the chemical bonds in the molecule. [1]

  5. Thermogravitational cycle - Wikipedia

    en.wikipedia.org/wiki/Thermogravitational_cycle

    The efficiency η of a thermogravitational cycle depends on the thermodynamic processes the working fluid goes through during each step of the cycle. Below some examples: If the heat exchanges at the bottom and top of the column with a hot source and cold source respectively, occur at constant pressure and temperature, the efficiency would be equal to the efficiency of a Carnot cycle: [1]

  6. Convection (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Convection_(Heat_transfer)

    The convection heat transfer mode comprises two mechanism. In addition to energy transfer due to specific molecular motion , energy is transferred by bulk, or macroscopic, motion of the fluid. This motion is associated with the fact that, at any instant, large numbers of molecules are moving collectively or as aggregates.

  7. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics , energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat .

  8. Electrostatic levitation - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_levitation

    Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity. It was used, for instance, in Robert Millikan 's oil drop experiment and is used to suspend the gyroscopes in Gravity Probe B during launch.

  9. Gravitoelectromagnetism - Wikipedia

    en.wikipedia.org/wiki/Gravitoelectromagnetism

    Gravitomagnetism is a widely used term referring specifically to the kinetic effects of gravity, in analogy to the magnetic effects of moving electric charge. [1] The most common version of GEM is valid only far from isolated sources, and for slowly moving test particles .
