Question
As shown in the figure below, a piston-cylinder assembly contains 1 kg of water at T1=200° C and
P1 = 1.5 bar holding the piston against the stops. The atmospheric pressure is 1 bar, and you can
assume the piston's weight is negligible.
The water is slowly cooled until the piston just begins to move downward in the cylinder. What is
the pressure (P2), temperature (T2), and volume (V2) of water at this point?
(°C), V2 =
P2 =
