Nitrogen (N2) gas within a piston-cylinder assembly undergoes a compression from p1 =0.2MPa, V1=2.75 m^3 to a state where p2 = 2 MPa. The relationship between pressure and volume during the process is pV^(1.35) = constant. For the N2, determine (a) the volume at state 2, in m^3, and (b) the work, in kJ.
