An ideal gas is trapped inside a test tube of cross-sectional area 20 × 10–6 m2 as shown in the figure. The gas occupies a height L1 at the bottom of the tube and is separated from air at atmospheric pressure by a mercury column of mass 0.002 kg If the tube is quickly turned isothermally upside down so that mercury column encloses the gas from below The gas now occupies height L1 in the tube. The ratio 
is [Take atmospheric pressure = 105 Nm–2]
