(8 pts) 10 moles of nitrogen are compressed adiabatically in a closed system from an initial pressure P,= 0.1 MPa and an initial temperature of T1 = 10 C to a final pressure of P=0.7 MPa. It is known that the compressor used has irreversibilities such that entropy generation is 5 J/mol K. You may assume nitrogen behaves as an ideal gas under these conditions, and that it has a constant heat capacity of Cp=29.1 J/mol K. a. Calculate the temperature of the gas at the end of the compressions. How much work in kJ) was required? b. Repeat the calculation, but now assume the compression is done reversibly. Discuss the differences in temperature and work between parts a) and b)
