Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using Mercury for the purpose.
1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent.
2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft.
3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.

What measures a barometer with Mercury?
A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.
What modern meteorological instrument measures atmospheric pressure?
A barometer is the modern meteorological instrument that is used to measure atmospheric pressure. It typically consists of a sealed glass tube filled with mercury that reacts to changes in pressure. The level of mercury in the tube rises and falls depending on the atmospheric pressure.
What instrument is used to collect air pressure data?
A barometer is the instrument used to measure air pressure. It typically consists of a glass tube filled with mercury, which rises or falls based on changes in air pressure. These changes are then converted into a reading that indicates the current atmospheric pressure.
What is a mercury barometer?
A mercury barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury, with one end submerged in a mercury bath. Changes in atmospheric pressure cause the level of mercury in the tube to rise or fall, which can be used to determine the current pressure readings.
What is the function of mercurial barometer?
A mercurial barometer measures atmospheric pressure by using a column of mercury in a glass tube. As air pressure changes, the level of mercury in the tube rises or falls, indicating the current atmospheric pressure. This information is used to provide weather forecasts and monitor changes in barometric pressure.

What instrument measures air pressure decreases during a storm?
Barometers measure air pressure.
An airtight instrument composed of thin sheets of metal used to measure air pressure?
aneroid barometer
What does Mercury borometer measure?
A mercury barometer measures atmospheric pressure by determining the height of a column of mercury that is supported by atmospheric pressure in a closed tube. By observing changes in this column height, meteorologists can track changes in atmospheric pressure over time.
How does the tomomoter work?
A barometer measures atmospheric pressure by using a column of mercury to indicate changes in pressure. As air pressure changes, it moves the mercury up or down in a tube. This movement is then converted into a numerical value representing the atmospheric pressure.

This information is used to provide weather forecasts and monitor changes in barometric pressure.
Why is pressure measured in mercury?
Pressure is measured in mercury because mercury is a dense liquid that is sensitive to changes in pressure. When pressure is applied, the height of the mercury in a column changes, allowing for accurate measurement of pressure levels.
Which instrument measures the air pressure using a metal chamber from which some air has been removed?
A barometer measures air pressure using a metal chamber from which some air has been removed. The most common type is the mercury barometer, where the air pressure pushes down on a pool of mercury in a glass tube to indicate atmospheric pressure.
