A 10 cm column of air is trapped by a column of Hg, 8 cm long, in a capillary tube horizontally fixed as shown below, at 1 atm pressure. Calculate the length of air column when the tube is fixed at the same temperature (a) vertically with open end uup (b) vertically with open end down .

A 10.0 cm column of air is trapped by a column of Hg 4.00 cm long in capillary tube of uniform bore when the tube is held horizontally in a room at 1 atm. Length of the air column when the tube is held vertically with the open end up is

If above tube is held vertical with open end upward then find the length of air column (in cm).

When an air column in a tube open at both the ends is set into vibration with

A metre long narrow bore held horizontally (and close 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?

In given figure, an ideal gas is trapped between a mercury column and the closed end of a uniform vertical tube. The upper end of the tube is open to the atmosphere. Initially the lengths of the mercury column and the trapped air colume are 12 cm and 50cm respectively. when the tube is titted solwly in a vertical plane through an angle of 30^(@) with horizontal then the new length of air colume is (x)/(41)m . Find x . Assuming the temperature to remains constant. (P_(atm) = 76 cm of Hg)

A small capillry tube of length 100cm closed at one end is kept horizontally and a mercury column of length 10cm is exactly in the middle. If the atmospheric pressure is 1 atm then identify the correct option(s).

Air is trapped in a horizontal glass tube by 36 cm mercury column as shown below : If the tube is held vertical keeping the open end up, lengh of air column shrink to 19 cm. What is the lengh (in cm) by which the mercury column shifts down?

A Quill's tube of one metre is taken. A certain amount of ideal gas is trapped in it by a 20 cm length of Hg column. When the tube is held vertical with open end upwards, the length of the gas column is 50 cm. Find the pressure and length of the trapped gas, when the Quill's tube is kept in slanting position making 45^(@) with the vertical open and upwards. (Take atmospheric pressure as 76 cm of Hg and sqrt(2)=1.414) .
