Question

Two different piston – cylinder devices each contain 1 kg of air. Initially, the temperature T = 300 K and pressure
P= 100 kPa of the gases are both the same in both cylinders. However, one of the cylinders is insulated and the other is
not.
Now, both of these gases inside the cylinders are let to expand in quasi-equilibrium processes until their pressures reach
to 50 kPa. The expansion process takes place isentropically in the cylinder 1 and in the cylinder 2 the expansion process
takes place reversible and isothermally.

a) Plot in Excel the P-V diagrams of both processes. (Take k = cp / cv = 1.4)

b) Calculate the work done by the gases
