The drawing shows a mercury
barometer. Consider two barometers, one using mercury and another
using an unknown liquid. Suppose that the pressure above the liquid
in each tube is negligible. The height of the unknown liquid is
18.8 times greater than the height of the mercury. Find the density
of the unknown liquid.

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...

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...

1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi.

Saturn's largest moon, Titan is actually larger than the planet Mercury. It is also one of the few bodies in the solar system that has a dense atmosphere. Data from the Voyager 1 probe indicates that the atmospheric pressure on Titan's surface is about 1.60x10^5 Pa, even though free-fall acceleration at Titan's surface is only 1.36m/s^2. Assuming that Titan's atmosphere has a uniform density of 2.32kg/m^3, at what height above the surface is Titan's atmospheric pressure equal to 1.01x10^5 Pa?
