Line 35: \sum_i \rho_i = 1. </math> # In the [[canonical ensemble]], the system is in [[thermal equilibrium]], so the average energy does not change over time; in other words, the average energy is ~~fixed~~constant ([[conservation of energy]]): <math display="block"> \langle E \rangle = \sum_i \rho_i E_i \equiv U . </math>
