WebNov 18, 2024 · In class we studied the degeneracy of energy level for a particle in various "boxes", including a rectangular three-dimensional one. Whenever we tried to quantify the degeneracy of the various energy levels, we did so "manually", by counting the amount of ways one could reach said energy level through different combinations.

WebAt lowest total energy (when the thermal energy of the particles is negligible), all the lowest energy quantum states are filled. This state is referred to as full degeneracy. This degeneracy pressure remains non-zero even at absolute zero temperature. Adding particles or reducing the volume forces the particles into higher-energy quantum states.
