One mole of an ideal gas with CP = (7/2) R and CV = (5/2) R expands from P1 = 8 bar and T1 = 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, (C, and AH for each process, Sketch each path on a single PV diagram.
