   How does a mercury barometer work?

   • A mercury barometer is an instrument used to measure atmospheric pressure in a certain location and has a vertical glass tube closed at the top sitting in an open mercury-filled basin at the bottom. Mercury in the tube adjusts until the weight of it balances the atmospheric force exerted on the reservoir.

   How does a mercury barometer measure atmospheric pressure?

   • At this point, equilibrium is established, and the height of the mercury column becomes a direct measure of atmospheric pressure. A higher column indicates higher pressure, while a lower column indicates lower pressure. Gravity plays a crucial role in the operation of mercury barometers.

   Can a barometer be used to measure altitude?

   • Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid. In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured.

   How many types of barometers are there?

   • There are two main types of barometers: mercury and aneroid. In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. To increase their accuracy, mercury barometers are often corrected for ambient temperature and the local value of gravity.

   Jul 3, 2022 · The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using water.
