The work done by the vapor on the piston is nearest:
The frictionless piston shown in its initial position provides a pressure of 600 kPa in the cylinder. Energy is added until the temperature reaches 250°C.
A) 65 J
B) 55 J
C) 45 J
D) 35 J
C) 45 J
There is no work done after the piston hits the stops. To lift the piston up to the stops, the work is
W = P(V2? V1 ) = 600×? × 0.022 × 0.06 = 0.0452 kJ
