The extra constant factor introduced in the denominator was introduced because, unlike the discrete form, the continuous form shown above is not dimensionless. As stated in the previous section, to make it into a dimensionless quantity, we must divide it by h 3 N (where h is usually taken to be the Planck constant).
Classical thermodynamics deals with states of dynamic equilibrium.The state of a system at thermodynamic equilibrium is the one for which some thermodynamic potential is minimized (in the absence of an applied voltage), [2] or for which the entropy (S) is maximized, for specified conditions.
Ross–Fahroo pseudospectral method — class of pseudospectral method including Chebyshev, Legendre and knotting; Ross–Fahroo lemma — condition to make discretization and duality operations commute; Ross' π lemma — there is fundamental time constant within which a control solution must be computed for controllability and stability
The equilibrium state is represented by the equation: + + If α is the fraction of dissociated electrolyte, then αc 0 is the concentration of each ionic species. (1 - α) must, therefore be the fraction of undissociated electrolyte, and (1 - α)c 0 the concentration of same. The dissociation constant may therefore be given as
If it is defined that a thermodynamic system is in thermal equilibrium with itself (i.e., thermal equilibrium is reflexive), then the zeroth law may be stated as follows: If a body C, be in thermal equilibrium with two other bodies, A and B, then A and B are in thermal equilibrium with one another.

This free expansion is irreversible but can be quasi-static for each chamber: quasi-equilibrium is retained for each part but not for the whole system The Joule expansion (a subset of free expansion ) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small ...
In physics, statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. Sometimes called statistical physics or statistical thermodynamics, its applications include many problems in the fields of physics, biology, [1] chemistry, neuroscience, [2] computer science, [3] [4] information theory [5] and ...
In thermodynamics, the thermodynamic free energy is one of the state functions of a thermodynamic system.The change in the free energy is the maximum amount of work that the system can perform in a process at constant temperature, and its sign indicates whether the process is thermodynamically favorable or forbidden.
