Air is compressed adiabatically in a piston–cylinder assembly from 1 bar, 300 K to 4 bar, 600 K. The air can be modeled as an ideal gas and kinetic and potential energy effects are negligible. Determine the amount of entropy produced, in kJ/K per kg of air, for the compression. What is the minimum theoretical work input, in kJ per kg of air, for an adiabatic compression from the given initial state to a final pressure of 4 bar? Note that work is positive into the compressor.
