  2. Reversible process (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Reversible_process...

    [a] While processes in isolated systems are never reversible, [3] cyclical processes can be reversible or irreversible. [4] Reversible processes are hypothetical or idealized but central to the second law of thermodynamics. [3] Melting or freezing of ice in water is an example of a realistic process that is nearly reversible.

  3. Reversible computing - Wikipedia

    en.wikipedia.org/wiki/Reversible_computing

    A process is said to be physically reversible if it results in no increase in physical entropy; it is isentropic. There is a style of circuit design ideally exhibiting this property that is referred to as charge recovery logic , adiabatic circuits , or adiabatic computing (see Adiabatic process ).

  4. Microscopic reversibility - Wikipedia

    en.wikipedia.org/wiki/Microscopic_reversibility

    First, it states that the microscopic detailed dynamics of particles and fields is time-reversible because the microscopic equations of motion are symmetric with respect to inversion in time ; Second, it relates to the statistical description of the kinetics of macroscopic or mesoscopic systems as an ensemble of elementary processes: collisions ...

  5. Cyclic voltammetry - Wikipedia

    en.wikipedia.org/wiki/Cyclic_voltammetry

    Many redox processes observed by CV are quasi-reversible or non-reversible. In such cases the thermodynamic potential E 0 1/2 is often deduced by simulation. The irreversibility is indicated by i pa /i pc ≠ 1. Deviations from unity are attributable to a subsequent chemical reaction that is triggered by the electron transfer.

  6. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    where a reversible path is chosen from absolute zero to the final state, so that for an isothermal reversible process Δ S = Q r e v T {\displaystyle \Delta S={Q_{rev} \over T}} . In general, for any cyclic process the state points can be connected by reversible paths, so that

  7. Stirling cycle - Wikipedia

    en.wikipedia.org/wiki/Stirling_cycle

    The cycle is the same as most other heat cycles in that there are four main processes: compression, heat addition, expansion, and heat removal. However, these processes are not discrete, but rather the transitions overlap. The Stirling cycle is a highly advanced subject that has defied analysis by many experts for over 190 years.

  8. First law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/First_law_of_thermodynamics

    For a particular reversible process in general, the work done reversibly on the system, ,, and the heat transferred reversibly to the system, , are not required to occur respectively adiabatically or adynamically, but they must belong to the same particular process defined by its particular reversible path, , through the space of thermodynamic ...

  9. Clausius–Clapeyron relation - Wikipedia

    en.wikipedia.org/wiki/Clausius–Clapeyron_relation

    Kelvin said of Carnot's argument that "nothing in the whole range of Natural Philosophy is more remarkable than the establishment of general laws by such a process of reasoning." [ 4 ] Kelvin and his brother James Thomson confirmed the relation experimentally in 1849–50, and it was historically important as a very early successful application ...
