Midterm Exam Problem 10 Example of using van der Waals
... For a Carnot cycle QH/QL = TH/TL so QH/TH − QL/TL = 0. Thus, if we approximate any reversible cycle (a) as an infinite sum of Carnot cycles as in (b), we see that the integral of dQ/T around a closed path is zero. This means that entropy is a state variable — like potential energy, the change in its ...
