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.

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?
