A piston-cylinder device contains 0.1 kg of a gas (PG model: c_v = 10.18, k = 1.4, R= 4.12 kJ/kg-K) at 1000 kPa and 300 K. The gas undergoes an isothermal (constant temperature) expansion process to a final pressure of 500 kPa.
(a) Determine the boundary work.
(b) The heat transfer.
(c) If heat is transferred from the surroundings at 300 K, determine the entropy generation during the expansion process.
