In a U-tube barometer, some air was left above the mercury in the closed tube. The difference in height between the column of mercury in the closed tube and im the open thbe is 75.6 cm when the atmospheric pressure is 78.9 cm of mercury. Calculate the air pressure in the space above the mercury in a closed tube. Express the presshre in dynes/cm^2

    Air pressure is measured by a barometer. One type of barometer utilizes an evacuated, calibrated tube inverted in a pool of mercury that is open to the atmosphere. As air pressure increases, the mercury will rise in the column until the weight of the mercury in the column equals the force exerted by the air on the surface of the pool. The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg ). According to this barometer,...

    A barometer is constructed using a closed-end tube containing a vacuum above a column of mercury. On a certain day, the pressure exerted solely by this column of mercury at the bottom of the tube is 1.024 x 10^5 Pa. Which quantity or quantities are equal to this measurement? A. neither the absolute pressure at the bottom and the atmospheric pressure B. the atmospheric pressure C. the absolute pressure at the bottom D. both the absolute pressure at the bottom...

  • A U-shaped tube open to the air at both ends contains some mercury.

    A U-shaped tube open to the air at both ends contains some mercury. A quantity of water is carefully poured into the left arm of the U-shaped tube until the vertical height \(h_{W}\) of the water column is \(22.0 \mathrm{~cm}\) as shown in (Figure 1)

  • The column of a mercury barometer is calibrated in linear units (such as inches or millimeters)...

    The column of a mercury barometer is calibrated in linear units (such as inches or millimeters) and thus the air pressure observed on such a barometer is reported in terms of these linear units. This measurement of pressure can be converted to other common pressure units. Some conversion factors are shown here. 1mm Hg = 1torr 1 atm = 760mm Hg 1 atm = 1.01325 bar 1 Pa = 10-5 bar 1 in = 2.54 cm 1 cm = 10...

    Pressure and Archimedes' Principle 2. Liquid mercury, which has a density of 13600 kg/m3, is commonly used in barometers to measure air pressure. A U-shaped tube closed at one end contains some mercury at the closed end (see figure) and vacuum above the mercury. Air in the open end exerts pressure on the mercury, and the mercury level rises until the mercury pressure in the closed end equals the air pressure in the open end. The height difference h between...

    A U-shaped tube is connected to a box at one end and open to the air at the other end. The box is full of gas at pressure pgas, and the tube is filled with mercury of density 1.36×104 kg/m3 . When the liquid in the tube reaches static equilibrium, the mercury column is h1 = 11.5 cm high in the left arm and h2 = 5.50 cm high in the right arm. Assume patmos=1.00atm. What is the gas pressure...
