3 Types of Ensembles (macrostates with fixed bulk properties)

A. Microcanonical ensemble - macrostate where N, U and V are unchanging (not very easy = number of particles, energy, and volume unchanging) b. Canonical ensemble - macrostate where N, T and V are unchanging (not quite MTV as it sounds least posh and expensive) c. Grand Canonical ensemble - macrostate where µ, T and V are unchanging (µTV as it sounds most posh and expensive - a boujee MTV) - in this µ is the chemical potential or Fermi level
