Multiplicity

The multiplicity, W, from the German

For systems, comprised of N identical particles, which satisfy the Boltzmann chaos assumption, the entropy of the system is found to be proportional to the multiplicity of the system:

**W**can refer to work done by force on a body, in physics or thermodynamics, or, in statistical mechanics and statistical thermodynamics, to the multiplicity or complexions of the particles of a Boltzmann-type systemMultiplicity

The multiplicity, W, from the German

*Wahrscheinlichkeit*(meaning probability), is the number of quantum states associated with the macrostate of a system. [1] The probability of a macrostate, for an isolated system, is proportional to its multiplicity.For systems, comprised of N identical particles, which satisfy the Boltzmann chaos assumption, the entropy of the system is found to be proportional to the multiplicity of the system:

S = k ln W
