One-tenth kmol of carbon monoxide (CO) in a piston- cylinder assembly undergoes a process from p1 5 150 kPa, T1 5 300 K to p2 5 500 kPa, T2 5 370 K. For the process, W 5 2300 kJ. Employing the ideal gas model, determine
(a) the heat transfer, in kJ.
(b) the change in entropy, in kJ/K.
Show the process on a sketch of the T-s diagram.
