13.2 Air in a weighted piston-cylinder device receives an unknown amount of work from the surroundings, while it loses 5 kJ of heat. State whether this is an open or closed system, then find the mass (in kg) and the network in (in kJ), also find the entropy generated (kJ/k) If Tb = 290K. Given Information P, = 2 bar V; -0.15 m T1 = 325 K W Q V, 0.15691 m Q = 5 kJ C, +0.712 kJ/kg-k C = 1.007 kJ/kg-k
