Nitrogen (N2) contained in a piston-cylinder arrangement, initially at 3 bar and 320 K, and a volume of 3.17 m undergoes a process to a final pressure of 1 bar. The pressure-volume relation is given by PV1.2 Constant. Assuming ideal gas behavior for nitrogen, determine (i) the mass of nitrogen, in kg. (10 points) and (ii) work during the process, in kJ (10 points) (iii) heat transfer during the process, in kJ (10 points). Neglect kinetic and potential energy effects. (Hint: This is from HW #3) 4
