A cylinder fitted with a frictionless piston contains 2 moles of ideal gas at 200 kPa and 150 C. The

gas is compressed isothermally but irreversibly to 800 kPa. The actual work required for compression is 30 % greater than the reversible work for the same compression. If the heat removed from the gas is discarded to a heat reservoir at 25 C, calculate the entropy generation.
