Robert F. Sekerka, in Thermal **Physics**, 2015 Abstract. An **ensemble** is a collection of microstates that are compatible with a specified macrostate of a thermodynamic system. The microcanonical **ensemble** represents an isolated system having fixed energy. For that **ensemble**, the fundamental assumption of statistical mechanics is that every compatible stationary quantum microstate is equally probable. canonical **ensemble**, in **physics**, a functional relationship for a system of particles that is useful for calculating the overall statistical and thermodynamic behaviour of the system without. **Ensembles** in Statistics. The formulation of statistical **ensembles** used **in physics** has now been widely adopted in other fields, in part because it has been recognized that the Boltzmann distribution or Gibbs measure serves to maximize the entropy of a system, subject to a set of constraints: this is the principle of maximum entropy.. 4.1: The Canonical **Ensemble** 4.2: Meaning of the Term "**Ensemble**" 4.3: Classical Monatomic Ideal Gas I've told you that it's easier to do calculations in the canonical **ensemble** than **in** the microcanonical **ensemble**. Today I'm going to demonstrate the truth of this assertion. 4.4: Energy Dispersion in the Canonical **Ensemble**.
