SOLVED: PROBLEM 1: Nitrogen (N2) gas within a piston-cylinder assembly undergoes compression from Pi = 10 bar and Vi = 0.5 m^3 to a state where Vf = 3 m^3. The relationship between pressure and volume during the process is pV constant. For the N2 gas, determine the pressure at state 2, in bar, and (b) the work, in kJ.

A piston-cylinder device contains 2.2 kg of nitrogen initially at 100 kPa and 25^∘ C. The nitrogen is now compressed slowly in a polytropic process during which P V^1.3= constant until the volume is reduced by one-half. Determine the work done and the heat transfer for this process. | Numerade
