Question

in the statement all spontaneous changes result in an increase in entropy, the entropy change is ______.

Explanation:

In thermodynamics, the second law states that for a spontaneous process in an isolated system, the entropy of the system increases (ΔS > 0). The statement refers to the entropy change of the system (or the universe, in some contexts) for spontaneous changes. So the entropy change here is of the system (or universe) and is positive (increase).

Answer:

of the system (or universe) and is an increase (ΔS > 0)
