widthof the rectangle DABC and the second is the height. So THE THERMODYNAMICS OF HEAT-ENGINES Therefore, in a rectangular entropy-temperature cyclesuch as this, the work done is measured by the areaenclosed. From this idea can be developed the proof that — In any closed entropy-temperature cycle… … Fig. 3 intermediate steps as a general principle. This can bedone by means of Fig. 3. In Fig. 3, let AB be any heat-process whatever. Equa-tion 2, transformed, gives dQ = TdN. (10) The right-hand member of this equation is representedgeometrically by the elementary vertical strip having the THE…
