Nitrogen (N.) gas within a piston-cylinder assembly undergoes a compression from p, =20 bar, V = 0.5 m³ to a state where V2 = 2.75 m³. The relationship between pressure

and volume during the process is pV35 = constant. For the N2, determine (a) the pressure at state 2, in bar, and(b) the work, in kJ.
