The working gas of a thermodynamic cycle is oxygen. In the original status the gas is given by the following status indicators: p1=105Pa , V1=10 liters, T1= 30o . As first step of the cycle the gas is warmed up to the pressure of keeping the volume fixed. After it the volume of the gas is extended to its double value keeping the pressure constant. Next step is: the gas is cooled down to the original pressure during the volume of the gas is fixed. Finally, the gas is gone back to the original status holding the pressure constant. What is the thermodynamic efficiency of the cycle and what is the work done during the whole thermal cycle?
