An ideal gas is trapped between a mercury column and the closed lower end of a narrowvertical tube of uniform bore. The upper end of the tube is open to atmosphere (atmosphericpressure 76 cm of Hg). The length of mercury and the trapped gas columns are 20 cm and 43cm respectively. What will be the length of the gas column when the tube is tilted slowly atconstant temperature in a vertical plane through an angle of 60°?
