Question
A weighted piston (total masa of 17 kg)., resting on stops in a cylnder (radius of 0.05 m) divides a container into two regions. 0.075 kg of saturated liquid water at 50 Cis contained
beneath the piston. The rest of the cylinder and container is evacuated. Heat is applied to the water until the piston is lifted off of the stops and moved a distance () of 0.6 m.
As the piston reaches the mouth of the cylinder, the hermetic seal is broken and the cylinder contents can now expand to fil the remainder of the evacuated space. At this instant,
no additional heat is added to or removed from the system. When the system fully equilibrates, its absolute pressure is measured to be 0.01 MPa
