1) In an open end manometer, one end of a U-tube filled with mercury is attached to a gas-filled container and the other end is open to the atmosphere. If the gas pressure in the container is less than atmospheric pressure a.Hg will be forced out of the open end of the U-tube. b.the Hg level will be higher in the arm connected to the container. c.the Hg level will be higher in the arm open to the atmosphere. d.the difference between the Hg levels in the two arms will be greater than 76 cm. 2) The apparatus is called a closed-end manometer because the arm not connected to the gas sample is closed to the atmosphere and is under vacuum. What is the pressure (in mm Hg) of the gas inside this apparatus, where the arm open to the atmosphere has a higher mercury level than the arm connected to the gas container, if the outside pressure, Patm, is 745 mm Hg and the difference in mercury levels, delta h, is 25 mm Hg? a.25 mm Hg b.720 mm Hg c.745 mm Hg d.770 mm Hg Since the mercury in the open arm is higher, the pressure for the bulb/gas container is 745 + 25 mm Hg = 770mm Hg, or greater than the open arm's pressure? Thanks.
