n moles of air are contained in a closed system at a temperature of 300 K, pressure of 1.5 bar and volume of 0.015 m. This system undergoes a thermodynamic cycle consisting of the following three reversible processes in series: (i) isothermal compression to a pressure of 5 bar, (ii) constant pressure heating, and (iii) constant volume cooling to the initial state. Assuming the air behaves ideally, and taking Cp = 20.8 J mol-1K-1 and C, = 12.5 J mol-K-1: %3D (a) Draw this cycle on a P-V diagram, labelling the isotherms and states. (b) Calculate T3, the temperature at the end of the isobaric heating (K). (c) Calculate the total work done by the entire cycle, W (J).
