a vertical cylinder of total lengh 100 cm is closed at the lower end and is fitted with a movable frictionless gas-tight disc at the other end.an ideal gas is trapped under the disc.initially the height of the gas column was 90cm when the disc was in equilibrium between the gas and the atmosphere.mercury is now slowly poured on the top of the discand it just started overflowing wen the disc descended through 32cm. find the atmospheric presure .Assume the temperature of the gas constant and neglet the thickness and weight of disc.
