Thermodynamic Expansion Examples by Yousif Abakar is a document available to read on EtoBox.

1) A 1 kg sample of air undergoes two expansion processes between the same initial and final states. The first does 20 kJ of work and receives 16 kJ of heat, changing internal energy by -4 kJ. The second requires only 9 kJ of heat, doing -13 kJ of work. 2) 0.75 kg of air at 3 bar and 125°C receives 900 kJ of heat at constant volume, raising its temperature to 1795°C and pressure to 15.6 bar. It then expands adiabatically, lowering its internal energy by 915 kJ. 3) A gas expands reversibly and adiabatically
