A confined quantity of air undergoes two thermodynamic processes departing from an initial equilibrium state where the temperature is 20°C, the absolute pressure is 1bar, and the volume is 0.2m3. First, the volume of the system is doubled by an isobaric process. Then, the volume is decreased back to the initial value through a process where the relation P-V1.4 is kept constant. You may assume average values for the particular heat capacities (cp and cv) to:
(a) Sketch the processes in a P-V diagram.
(b) Determine the temperature of the three states in K.
(c) Calculate the total work in kJ.
(d) Compute the total heat transfer in kJ.
