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.

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.

A thin tube, sealed at both ends, is 100 cm long. If lies horizontally, the middle 10 cm containing mercury and the two equal containing air at stan-dard atmospheric pressure. If the tube is now turned to a verical position, by what amount will the mercury be displaced ?

A thin tube sealed at both ends is 90 cm long. It is kept horizontally, the middle 10cm containing mercury and the two equal ends containing air at standard atmospheric pressure. The tube is turned and kept in vertical position. By what amount will the mercury be displaced?

A thin tube of uniform cross-section is sealed at both ends. It lies horizontally, the middle 5 cm containing mercury and the two equal end containing air at the same pressure P. When the tube is held at an angle of 60^@ with the vetical direction, the length of the air column above and below the mercury column are 46 cm and 44.5 cm respectively. Calculate the pressure P in centimeters of mercury. (The temperature of the system is kept at 30^@C ).
