Problem 3 (20 points): The state of an ideal gas with Cp = (5/2)R is changed from P = 1 bar and V1 = 12 m^3 to P2 = 12 bar and V2 = 1 m^3 by the following mechanically reversible processes:
(a) Isothermal compression.
(b) Adiabatic compression followed by cooling at constant pressure.
(c) Adiabatic compression followed by cooling at constant volume.
(d) Heating at constant volume followed by cooling at constant pressure.
(e) Cooling at constant pressure followed by heating at constant volume.
Calculate the work done (W) and the change in enthalpy (ΔH) for each of these processes.
