(1)A uniform tube closed at one end, contains a pallet of mercury 10cm long. When the tube is kept vertically with the closed end upward, the length of the air column trapped is 20cm. Find the length of air column trapped when the tube is inverted so that the closed end goes down. Atmospheric pressure = 75cm of mercury. (2)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 27degrees C and at a pressure 76cm of mercury. The air column on one side is maintained at 0 deg C and the other side is maintained at 127deg C. Calculate the length of air column on the cooler side. Neglect the changes in the volume of the mercury and of the glass. (3)An ideal gas is trapped between a mercury column and the closed end of a narrow vertical tube of uniform base containing the column. The upper end of the tube is open 2 the atmosphere. The atmospheric pressure equals 76cm of mercury. The lengths of mercury column and the trapped air column are 20cm and 43cm respectively. What will be the length of the air column when the tube is tilted slowly in a vertical plane through an angle of 60degrees? assume the temperature 2 remain constant.
