Nitrogen (N2) initially occupying 0.1 m3 at 6 bar, 2478C undergoes an internally reversible expansion during which pV 1.20 5 constant to a final state where the temperature is 378C. Assuming the ideal gas model, determine
(a) the pressure at the final state, in bar.
(b) the work and heat transfer, each in kJ.
(c) the entropy change, in kJ/K.
