Total particle count is sum of occupancies¶
Maxwell—Boltzmann, Fermi—Dirac and Bose—Einstein distributions describe the average number of particles in some energy level or particle state. They are normalized by the condition that the sum of the number of particles in each energy level or particle state should be equal to the total number of particles in the system.
Notes:
This law can be used to express chemical potential \(\mu\) as a function of temperature \(T\) and total particle count \(N\) for Fermi—Dirac and Bose—Einstein distributions.
