5. The initial volume for Nitrogen gas in a piston cylinder is 0.75 m³ with an initial pressure and temperature of 0.2 MPa, and 240 K respectively, which undergoes an internally reversible compression during which PV12=constant to a final state where temperature is 400 K. Assuming the ideal gas model, determine: (18 points) (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
