7 unusual facts about Thermodynamic equilibrium


Chapman–Enskog theory

Chapman-Enskog theory presents accurate formulas for a multicomponent gas mixture under thermal and chemical equilibrium.

Eta Corvi

A large amount, at least 3 x 1019 kg, of 0.1 – 1000 µm warm dust is present, in a roughly collisional equilibrium distribution with dn/da ~ a-3.5.

Navarro–Frenk–White profile

The NFW profile is an approximation to the equilibrium configuration of dark matter produced in simulations of collisionless dark matter particles by numerous groups of scientists.

State postulate

The state postulate is a term used in thermodynamics that defines the given number of properties to a thermodynamic system in a state of equilibrium.

Thermodynamic equilibrium

M. Zemansky also distinguishes mechanical, chemical, and thermal equilibrium.

Virial expansion

The classical virial expansion expresses the pressure of a many-particle system in equilibrium as a power series in the density.

Wulff construction

The Wulff construction is a method for determining the equilibrium shape of a droplet or crystal of fixed volume inside a separate phase (usually its saturated solution or vapor).


Labradorite

This labradorescence, or schiller effect, is the result of light diffraction within the lamellar intergrowths – fine, adjacent layers of the separate materials (lamellae) comprising the whole rock phase – created when conditions do not allow for sufficient diffusion to the materials' equilibrium composition.
