3.17. One mole of an ideal gas with Cp (7/2)R and Cy (5/2)R expands from P, 8 bar and T 600 K to P2 = 1 bar by each of

the following paths: (a) Constant volume; (b) Constant temperature; (c) Adiabatically. Assuming mechanical reversibility, calculate W, Q. AU, and AH for each process.Sketch each path on a single PV diagram.
