Unformatted text preview: H at point B. The expansion is isothermal, that is, performed at a constant temperature. Now, the gas is expanded further, but at constant entropy. The temperature falls to l during this isentropic process and arrives at point C. The gas is then compressed isothermally to point D, and is compressed isentropically back to point A, thus completing one cycle. The total work accomplished by the system can be written from our previous results as W = h . Looking at the figure again, we see that this is merely the area enclosed by the rectangle. This yields a nice graphical method of understanding a simple version of a heat engine. Figure %: A Carnot Cycle...
