3.10. An ideal gas, CP=(5/2)R and CV=(3/2)R, is changed from P=1 bar and Vt=12m3 to P2=12 bar and V2=1m3 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. 3.10.
