A piston–cylinder assembly contains 1 kg of nitrogen gas (N2). The gas expands from an initial state where T1 = 700 K and p1 = 5 bar to a final state where p2 = 2 bar. During the process the pressure and specific volume are related by pv1.3 = constant. Assuming ideal gas behavior and neglecting kinetic and potential energy effects, determine the heat transfer during the process, in kJ, using
(a) a constant specific heat evaluated at 300 K.
(b) a constant specific heat evaluated at 700 K.
(c) data from Table T-11.
