A piston-cylinder assembly contains propane, initially at 27 °C,
1 bar, and a volume of 0.2 m3 . The propane undergoes a process to
a final pressure of 6 bar, during which the pressure-volume
relationship is pV1.1 = constant. For the propane, evaluate the
work and heat transfer, each in kJ. Kinetic and potential energy
effects can be ignored.
