Question

Quizplus · Accepted Answer

1) True, because for a reversible process, the entropy change is only dependent on the heat exchanged and the temperature at which it is exchanged.
2) True, because for a spontaneous process, the entropy change of the universe always increases.
3) True, because for a reversible process, the change in entropy during a phase change can be calculated using the equation: ΔS = q/T.
