H3.3 A frictionless piston-cylinder device contains 2 kg of H2O initially at T1 = 300◦C and p1 = 5 bar. The device is cooled at constant pressure until the volume is ∀2 = 0.5 m3 . Assume a quasiequillibrium process which occurs slowly with no acceleration as the piston moves. Kinetic and potential energy effects are negligible. Determine: a. work [kJ] during process (indicate magnitude and direction) b. heat transfer [kJ] during process (indicate magnitude and direction)
