One mole of an ideal gas with CP = (7/2)R and CV = (5/2)R expands form P1 = 8 bar and T1 = 600 K to P2 = 1 bar by each of the following paths: (a) Constant volume. (b) Constant temperature, (c) Adiabatically. Assuming mechanical reversibility. Write a Matlab code that simulates the three processes described and produce a plot of the PV diagram.
