CARNOT CYCLE ON DIFFERENT SCALES

The present review highlights the detailed description of Carnot cycle on pressure-volume, pressure-entropy, temperature-pressure, volume-temperature, entropy-volume, internal energy-temperature and temperature entropy scale. The Carnot cycle involve four different steps a) isothermal reversible expansion, b) adiabatic reversible expansion, c) isothermal reversible compression and d) adiabatic reversible compression. Carnot cycle and its working in different articles and books were mainly given on pressure-volume scale only. On each of seven scales (P-V, P-S, T-P, V-T, S-V, U-T & T-S) the overall reversible Carnot cycle is explained by combining four different reversible steps.
