    en.wikipedia.org/wiki/Thermodynamic_equations

    The behavior of a thermodynamic system is summarized in the laws of Thermodynamics, which concisely are: . Zeroth law of thermodynamics; If A, B, C are thermodynamic systems such that A is in thermal equilibrium with B and B is in thermal equilibrium with C, then A is in thermal equilibrium with C.

    For quasi-static and reversible processes, the first law of thermodynamics is: d U = δ Q − δ W {\displaystyle dU=\delta Q-\delta W} where δQ is the heat supplied to the system and δW is the work done by the system.

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    The laws of thermodynamics are the result of progress made in this field over the nineteenth and early twentieth centuries. The first established thermodynamic principle, which eventually became the second law of thermodynamics, was formulated by Sadi Carnot in 1824 in his book Reflections on the Motive Power of Fire.

    en.wikipedia.org/wiki/State_function

    In the thermodynamics of equilibrium, a state function, function of state, or point function for a thermodynamic system is a mathematical function relating several state variables or state quantities (that describe equilibrium states of a system) that depend only on the current equilibrium thermodynamic state of the system [1] (e.g. gas, liquid, solid, crystal, or emulsion), not the path which ...

    en.wikipedia.org/wiki/Heat_equation

    In mathematics, if given an open subset U of R n and a subinterval I of R, one says that a function u : U × I → R is a solution of the heat equation if = + +, where (x 1, ..., x n, t) denotes a general point of the domain.

  9. Third law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Third_law_of_thermodynamics

    One can think of a multistage nuclear demagnetization setup where a magnetic field is switched on and off in a controlled way. [11] If there were an entropy difference at absolute zero, T = 0 could be reached in a finite number of steps. However, at T = 0 there is no entropy difference, so an infinite number of steps would be needed. The ...
