A piston-cylinder apparatus contains argon at initial conditionsof 15 psia, 70F, and 0.30 ft3. The argon is thencompressed slowly and frictionlessly to a final pressure of 150psia. Heat transfer between the argon and the surroundings at 60Fcauses the temperature to remain constant throughout thecompression process. Determine (a) the argon mass (lbm), (b) thefinal volume (ft3), (c) the work for the process(ft-lbf), (d) the heat transfer (BTU), and (f) the total entropygeneration for the process (BTU/R). (f) Why is this processirreversible?
