As shown in the figure below, a gas contained within a piston-cylinder assembly, initially at a volume of 0.1 m3, undergoes a constant-pressure expansion at p 2 bar to a final volume of V2 0.2 m3, while being slowly heated through the base. The change in internal energy of the gas is 0.25 kJ. The piston and cylinder walls are fabricated from heat-resistant material, and the piston moves smoothly in the cylinder. The local atmospheric pressure is 1 bar. Piston-...
A gas contained within a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where p1=10 bar, V1= 0.1 m3, U1=400 kJ and p2=1 bar, V2=1.0 m3, U2=200 kJ: Process A. Process from 1 to 2 during which the pressure-volume relation is p.V = constant.
