Vor 3 Tagen · Die Entropie ist eine in der Thermodynamik definierte physikalische Größe von fundamentaler Bedeutung. Sie ist eine der Zustandsgrößen eines makroskopischen Systems und hat unter anderem folgende Eigenschaften:
Vor einem Tag · Entropy in information theory is directly analogous to the entropy in statistical thermodynamics. The analogy results when the values of the random variable designate energies of microstates, so Gibbs's formula for the entropy is formally identical to Shannon's formula. Entropy has relevance to other areas of mathematics such as
Vor 6 Tagen · Thermodynamics is a branch of physics concerned with heat and temperature and their relation to other forms of energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question. Thermodynamics has its basic ...
Vor 4 Tagen · Heat equation. Animated plot of the evolution of the temperature in a square metal plate as predicted by the heat equation. The height and redness indicate the temperature at each point. The initial state has a uniformly hot hoof-shaped region (red) surrounded by uniformly cold region (yellow). As time passes the heat diffuses into the cold region.
Vor 5 Tagen · In contrast, in Thermodynamics, no arbitrary decisions can be taken concerning entropy generation, energy transfer interactions inducing changes in the thermodynamic system’s properties that always lead to positive, or in the ideal reversible limit null entropy generation.

Vor 3 Tagen · In LTS, the thermodynamic coordinates of motion can be identified either in terms of thermodynamic fluxes appearing in the expression of entropy source strength, or the choice can be based on the suitable Gibbs relation, keeping in mind that irreversible thermodynamics constitutes an autonomous system of description, that is, all thermodynamic quantities are time dependent only through their ...
