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,...

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

A glass ball of volume 1.9m3m3 is connected a U-shaped tube with one end open to the atmosphere. The tube is filled with a liquid of density 4097 kgm3kgm3. 71.3 moles of a monatomic ideal gas are inside the glass ball. The liquid is a height 1.5cm above the bottom of the tube on the side closer to the atmosphere, and 15.6 cm above the bottom of the tube on the side of the glass ball. Atmospheric pressure is 1.03914×105Pa×105Pa....
