A horizontal uniform glass tube of `100cm` length is sealed at both ends contains `10 cm` mercury column in the middle , the temperature and pressure of air on either side of mercury column are repectively `31^(@)C` and `76cm` of mercury, if the air column at one end is kept at` 0^(@)C` and the other end at `273^(@)C` then pressure if air which is `0^(@)C` is
(in `cm` of `Hg`)

The temperature and pressure at Simla are 15.0^(@)C and 72.0cm of mercury and at Kalka these are 35.0^(@)C and 76.0 cm of mercury. Find the ratio of air density at Kalka to the air density at Simla.

A long horizontal glass capillary tube open at both ends contains a mercury thread 1 m long at 0^@C . Find the length of the mercury thread, as read on this scale, at 100^@C .

A vertical uniform U tube open at both ends contains mercury. Water is poured in one limb until the level of mercury is depressed 2cm in that limb. What is the length of water column when this happens.

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).

A glass tube sealed at both ends is 100cm long, It lies horizontally with the middle 10cm containing mercury. The two ends of the tube contain air at 27^(@)C and at a pressure 76cm of mercury. The air column on one side is maintained at 0^(@)C and the other side is maintained at 127^(@)C . Calculate the length of the air column on the cooler side. neglect the changes in the volume of mercury and of the glass.

The readings of a thermometer at 0^(@)C and 100^(@)C are 50 cm and 75 cm of mercury column respectively. Find the temperature at which its reading is 80 cm of mercury column ?

A narrow uniform glass tube 80 cm long and open at both ends is half immersed in mercurry. Then the top of the tube is closed and it is taken out of mercury. A column of mercury 22 cm long then remains in the tube. What is the atmospheric pressure?

In the given figure a glass tube lies horizontally with the middle 20cm containing mercury. The two ends of the tube contains air at 27^(@)C and at a pressure 76 cm of mercuy. Now the air column on one side in maintained at 0^(@)C and the other side is maintained at 127^(@)C . Find the new length of the air column on the cooler side. Neglect the changes in the volume of mercury and of the glass.

The height of mercury which exerts the same pressure as 20 cm of water column, is
