The grand canonical ensemble accommodates states of varying vitality and various numbers of particles; the completely different states within the ensemble are accorded totally different probabilities depending on their total energy and complete particle numbers. For systems containing many particles (the thermodynamic limit), all three of the ensembles listed above tend to provide similar behaviour. It is then merely a matter of mathematical convenience which ensemble is used. Giant techniques at a part transition. Large programs with lengthy-vary interactions. In these circumstances the proper thermodynamic ensemble have to be chosen as there are observable variations between these ensembles not simply
