- A barometer is an instrument used to measure atmospheric pressure12345. It typically consists of a glass tube filled with mercury or another liquid, inverted and immersed in a container of the same liquid. The height of the liquid column indicates atmospheric pressure1245. Mercury is commonly used due to its nonvolatility and high density35.

The tube and dish are filled with mercury (HG) or some other liquid, and the tube is inverted into the dish. If all this is done without any air entering the tube, a column of liquid will remain above the dish.www.sparknotes.com/chemistry/gases/pressure/se…We can measure atmospheric pressure, the force exerted by the atmosphere on the earth’s surface, with a barometer (Figure 9.4). A barometer is a glass tube that is closed at one end, filled with a nonvolatile liquid such as mercury, and then inverted and immersed in a container of that liquid.openstax.org/books/chemistry-2e/pages/9-1-gas-pr…We use mercury in barometers because it's more convenient than using water. Water is less dense (less heavy, in effect) than mercury so air pressure will lift a certain volume of water much higher up a tube than the same volume of mercury.www.explainthatstuff.com/barometers.htmlBarometer is an instrument that measures atmospheric pressure. A mercury barometer is a closed tube filled with mercury inverted in a mercury reservoir. The height of the mercury column indicates atmospheric pressure (with 1 atm = 760 mm of mercury). An aneroid barometer consists of an evacuated container with a flexible wall.glossary.periodni.com/glossary.php?en=barometerThese barometers are commonly simple designs: a glass tube upside-down in a wide and flat glass bowl, both filled with mercury. Mercury (Hg) is the most common liquid for barometers and manometers because it is nonvolatile (does not evaporate easily) and has a high density.chemistrytalk.org/barometers-and-manometers/ 2.11: The Barometric Formula - Chemistry LibreTexts
