A 10 cm column of air is trapped by a column of mercury, 8 cm long, in a capillary tubehorizontally fixed as shown below, at 1 atm pressure. When the tube is held atcertain angle theta^@ with open end up, the weight of Hg is borne partially by the gas. Vertical Height of Hg is a measure of additional pressure on gas. When the tube's held at 45^@ with the horizontal with open end up the length of air column is
