In a vertical cylindrical vessel above the piston A, there is a gas enclosed by
the piston B, on which a liquid of the plane p is poured up to the top of the
cylinder. How far x should the piston A be raised so that a column of liquid
of height H remains above the piston B? The mass of the piston B and its
friction against the walls should be ignored. Atmospheric pressure P , initial
0
height of the liquid column H , gas column h . The gas temperature does not
0 0
change when the piston is displaced.
