A metre long narrow bore held horizontally (and closed at one end) contains a 76 cm long mercury thread, which traps a 15 cm column of air. What happens if the tube is held vertically with the open end at the bottom ?

Nearly 24 cm of mercury flows out, and the remaining 52 cm of mercury thread plus the 48 cm of air above it remain in equilibrium with the outside atmospheric pressure (We assume there is no change in temperature throughout).
A glass tube of uniform area of cross section and open at one end encloses some air at 27^@C by a 4 cm long mercury thread that acts like a piston. When the tube is held vertical with its open end up length of the air column in the tube is 9 cm.When the open end is held downwards by turning the tube,the length of the enclosed air column becomes 10 cm. Find () the value of the atmospheric pressure (ii) the temperature at which the length of the air column becomes 9cm again,while the tube is still held inverted.
A uniform glass tube closed at one end contains some air at 27^@C confined by a mercury thread of length 4 cm. When the tube is held vertically with its open end at the top,the length of the confined air column is 9cm. IF the tube is inverted then the length of that air column becomes 10 cm. Determine the atmospheric pressure.
A uniform tube closed at one end contains some air confined by a mercury thread of length 15 cm. When the tube is held vertically,with the open end at the top,the air column is 10 cm long at 27^@C . IF the tube is inverted, the length of the air column becomes 15 cm. At what temperature will the air column be 20 cm long in its inverted position.
A narrow tube of uniform cross-section is closed at one end.Inside this tube a mercury thread of length hcm detaches some air from the atmosphere outside.When the tube is held vertical keeping its closed ends up,the length of the confined air column becomes l_1 cm.Again the length of the air column becomes l_2 cm. When the tube is held vertical keeping it open end up.Find the magnitude of the atmosphere spherical pressure.
In a capillary tube,closed at one end,some air is enclosed by a mercury thread of length 10 cm. When the tube is kept horizontal the length of the air column is 17 cm. When it is held vertical with the open ends up,the length changes to 15 cm,what will be the length of the air column when the tube is held vertical with the open ends downwards?
A horizontal glass tube, sealed at both ends contains a column of mercury of length 10 cm at its middle. The two ends of the tube contain air at a pressure of 76 cmHg. IF the tube is held in a vertical position what will be the shift of the mercury column? Length of the capillary tube=100 cm.
At standard condition 40 cm^3 of oxygen gas is introduced into a tube closed at one end and having a cross sectional area of 1.2 cm^2 . The open end is dipped in mercury and the tube is held vertically. The mercury meniscus in the tube stands at a height of 15.6 cm above the surface of mercury kept in the trough.IF the atmospheric pressure is 75.6 cm and the room temperature is 31^@C then what the length of the tube was filled with the gas?
A 100 cm long stretched string is struck at a point 25 cm from one of its ends. Which of the overtones would be absent in the emitted notes ?
A long horizontal glass capollary tube open at both ends contains a mercury thread 1m long at 0^@ C. A scale is etched on the glass tube. This scale is correct at 0^@ C. Find the length of mercury thread, as shown by this scale at 100^@C Also find original lenght of thread at 100^@ C ( gamma_(mercury)=18.2xx10^(-5)K^1, alpha__(glass)=9xx10^-6 K^(-1))
A uniform narrow tube closed at one end contains some air confined by a mercury column. The length of the column is 10 cm at 20^@C IF the temperature is increased to 70^@C , then what will be the shift of the mercury column? gamma_p=0.00366^@C^-1
