One-quarter lbmol of nitrogen gas (N2) undergoes a
process from p1=20 lbf/in², T1= 500ºR to p2=150 lbf/in²,
T2= 800ºR. For the process W=-500 Btu. Employing the
ideal gas model, determine:
(a) the heat transfer, in Btu.
(b) the change in entropy, in Btu/ºR.
(c) Show the initial and final states on a T–s diagram.
