Nitrogen (N2) gas within a piston–cylinder assembly undergoes a process from p1 = 20 bar, V1 = 0.5 m3 to a state where V2 = 1.75 m3. The relationship between pressure and volume during the process is pV1.35 = constant. For the N2, determine (a) the pressure at state 2, in bar, and (b) the work, in kJ.

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
