Description
A canonical ensemble is the group of compartments enclosed in an isolated system H, with a smaller compartment A1 in thermal equilibrium with a larger compartment A2 which is the heat reservoir at temperature T. When A1 is large in the canonical sense, if its state can be described in terms of macroscopic thermodynamic quantities of V, T, and p merging with the state described as a probability distribution.
