A vertical cylinder of height 100cm contains air at a constant temperature and its top is closed by a frictionless pistion at atmospheric pressure (76cm of Hg) as shown figure (a). If mercury is slowly poured on the pistion, due to its weight air is compressed. Find the maximum height of the mercury column which can be put on the pistion.
