Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The microcanonical ensemble is the equilibrium ensemble selected by isolation and fixed conserved quantities, including an energy shell.

How to interpret this relation type

The target is a member or subtype of the broader source class.

Microcanonical ensembleBoltzmann entropy

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

For a specified energy shell or macrostate, Boltzmann entropy is the logarithm of the compatible state count or phase-space volume times kBk_{\mathrm B}.

How to interpret this relation type

The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
