A glass capillary tube sealed at both ends is 100cm long. It lies horizontally with the middle 10 cm containing mercury. The two ends of the tube which are equal in length contain air at 27°C at apressure of 76cm of Hg. Now the air column at one end of the tube is kept at 0^(@) C and the other endis maintained at 127^(@) C. Calculate the pressure of the air column at 0^(@) C. (Neglect the change in volume of Hg and glass).

1.	A glass capillary tube sealed at both ends is 100cm long. It lies horizontally with the middle 10 cm containing mercury. The two ends of the tube which are equal in length contain air at 27°C at apressure of 76cm of Hg. Now the air column at one end of the tube is kept at 0^(@) C and the other endis maintained at 127^(@) C. Calculate the pressure of the air column at 0^(@) C. (Neglect the change in volume of Hg and glass).
