Question

A weighted piston (total mass of 16.8 kg), resting on stops in a cylinder (radius of 0.05 m) divides a container into two regions. 0.075 kg of saturated liquid water at 50 "C is contained beneath the piston. The rest of the cylinder and container is evacuated. Hea s applied to the water ї he son s te orof sto sam moved a distance (y) 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 fill 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. vacuum CC LY-1NS-EA Niel Crews, 2013 a) What is the state of the water when the piston begins to rise off of the stops compressed liquid b) What is the water temperature when the piston reaches the mouth of the cylinder? 61.02432C BONUS: c) What is the final volume of the water (after the seal is broken)? 76.35
