  2. Surface energy transfer - Wikipedia

    en.wikipedia.org/wiki/Surface_energy_transfer

    The SET rate follows the inverse of the fourth power of the distance [2] = where ⁠ ⁠ is the donor emission lifetime; ⁠ ⁠ is the distance between donor-acceptor; ⁠ ⁠ is the distance at which SET efficiency decreases to 50% (i.e., equal probability of energy transfer and spontaneous emission).

  3. List of set identities and relations - Wikipedia

    en.wikipedia.org/wiki/List_of_set_identities_and...

    This article lists mathematical properties and laws of sets, involving the set-theoretic operations of union, intersection, and complementation and the relations of set equality and set inclusion. It also provides systematic procedures for evaluating expressions, and performing calculations, involving these operations and relations.

  4. Transfer of energy - Wikipedia

    en.wikipedia.org/wiki/Transfer_of_energy

    Transfer of energy may refer to: Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. Heat transfer, the exchange of thermal energy via conduction, convection and radiation; Collision, an event in which two or more bodies exert forces on each other over a relatively short time

  5. First law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/First_law_of_thermodynamics

    The first law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes.The law distinguishes two principal forms of energy transfer, heat and thermodynamic work, that modify a thermodynamic system containing a constant amount of matter.

    A set of polygons in an Euler diagram This set equals the one depicted above since both have the very same elements.. In mathematics, a set is a collection of different [1] things; [2] [3] [4] these things are called elements or members of the set and are typically mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other ...

  7. Thermodynamic system - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_system

    To account for the internal energy of the open system, this requires energy transfer terms in addition to those for heat and work. It also leads to the idea of the chemical potential . A wall selectively permeable only to a pure substance can put the system in diffusive contact with a reservoir of that pure substance in the surroundings.

  9. Thermodynamic process - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_process

    Energy gained by the system, through work done on it, is lost to the bath, so that its temperature remains constant. An adiabatic process is a process in which there is no matter or heat transfer, because a thermally insulating wall separates the system from its surroundings. For the process to be natural, either (a) work must be done on the ...
