Entropy Production

Some articles on entropy production, entropy:

Joule Expansion - Entropy Production
... It is awkward to calculate the entropy production in this process directly, because the route that the expansion takes in the time between the partition ... However, entropy is a function of state, and therefore the entropy change can be computed directly from the knowledge of the final and initial equilibrium states ... For an ideal monatomic gas, the entropy as a function of the internal energy U, volume V, and number of moles n is given by the Sackur–Tetrode equation In this expression m the particle mass and ...
Detailed Balance and The Entropy Growth
... kinetics, detailed balance provides sufficient conditions for the entropy growth in isolated systems ... to the Boltzmann equation, the principle of detailed balance implies positivity of the entropy production ... The Boltzmann formula (1872) for the entropy production in the rarefied gas kinetics with detailed balance served as a prototype of many similar formulas for dissipation in mass action kinetics and generalized mass ...
Entropy (classical Thermodynamics) - Entropy Change in Irreversible Transformations
... See also exergy See also entropy production We now consider inhomogeneous systems in which internal transformations (processes) can take place ... If we calculate the entropy S1 before and S2 after such an internal process the Second Law of Thermodynamics demands that S2 ≥ S1 where the equality sign holds if the process is reversible ... The difference Si = S2 - S1 is the entropy production due to the irreversible process ...
Abiogenesis - Current Models - Origin of Organic Molecules - Ultraviolet and Temperature-assisted Replication Model
... thermodynamic process which arises and persists because it produces entropy ... Entropy production is not incidental to the process of life, but rather the fundamental reason for its existence ... Present day life augments the entropy production of Earth by catalysing the water cycle through evapotranspiration ...

Famous quotes containing the words production and/or entropy:

    The repossession by women of our bodies will bring far more essential change to human society than the seizing of the means of production by workers.
    Adrienne Rich (b. 1929)

    Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy.
    Václav Havel (b. 1936)
