Entropy of liquid water from ab initio molecular dynamics.

WebThe initial number of microstates is one, the final six: Δ S = k ln W c W a = 1.38 × 10 −23 J/K × ln 6 1 = 2.47 × 10 −23 J/K. The sign of this result is consistent with expectation; since there are more microstates possible for the final state than for the initial state, the change in entropy should be positive.
