A glass tube with a sealed end is completely submerged in a vessel with mercury. The air column is 15 cm long. The what height (in cm) must the upper end be raised above the level of Hg so that the level of Hg inside the tube is at the level of Hg in the veseel ?
[Atmospheric pressure = 75 cm of Hg column]

A tube of length 50 cm is containing a gas in two secitons separated by a mercury column of length 10 cm as shown in figure. The tube's open end is just inside the Hg surface in container, find pressure of gas in upper section. [Assume atmospheric pressure = 75 cm of Hg column]

A vertical tube of length 100 cm contains a mercury pallet of length 5 cm as shown in the figure. The length of the tube above mercury pallet if the tube is inverted is nearly: (atmospheric pressure = 75 cm Hg of Hg)

An open glass tube is immersed in mercury in such a way that a lenth of 8cm extends above the mercury level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additional 46cm. What will be length of the air column above mercury in the tube now? (Atmosphere pressure =76cm of Hg)

(Atmosphere pressure =76cm of Hg)

An open glass tube is immersed in mercury in such a way that a length of 8 cm extends above the mercury level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additonal 46 cm. What will be length of the air column above mercury in the tube now? (Atmospheric pressure = 76 cm of Hg
