A confined quantity of ideal gas with R=0.3 kJ/kgK and constant Cv= 0.7Kj/KgK
undergoes a power cycle consisting of two thermodynamic processes from an initial equilibrium state where the temperature is 27 c and the absolute pressure is 1 bar. First, the system is compressed to one tenth ( 1/10) of its initial volume in a process where the relationship PV^1.4 is maintained constant . Then, the system is taken back to its initial condition in a process where the pressure and volume are related linearly (P=aV+b).
