WebThe minimum surprise is when p = 0 or p = 1, when the event outcome is known ahead of time, and the entropy is zero bits. When the entropy is zero bits, this is sometimes referred to as unity, where there is no uncertainty at all - no freedom of choice - no information. Other values of p give entropies between zero and one bits. WebBecause the change in entropy is Q/T, there is a larger change in Δ S Δ S at lower temperatures (smaller T).
