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 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 is the most commonly used barometer?
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
When air pressuer increases what does the mercury in the barometer do?
Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.
Mercury barometer means you will have what kind of day?
A mercury barometer is an instrument which can be used to forecast the weather. The fact that there is a barometer does not affect the weather. You need to see what the barometer shows and interpret it.
What is a barometer with Mercury called?
A mercury barometer.
What does a barometer has in it?
barometer has mercury inside it .
What type of barometer was invented first the aneroid or the mercury?
The mercury barometer was invented first, in 1643 by Evangelista Torricelli. The aneroid barometer was invented later, in 1844 by Lucien Vidi.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
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.
Which statement accurately describes a difference between a mercury barometer and an aneroid barometer?
A mercury barometer uses a column of mercury to measure atmospheric pressure, while an aneroid barometer uses a flexible metal box to measure pressure changes. Mercury barometers are more accurate but require careful handling due to the toxic nature of mercury, while aneroid barometers are portable and safer to use.
How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
What is the most commonly used barometer?
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
Why does Mercury stay in the barometer?
A barometer is a closed-system vacuum that allows the mercury to expand with changes in temperature and pressure.
Torricelli invented a device for measuring air pressure called a(n)?
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
What did evangelista torricelli discover?
BAROMETER ---- It's actually a mercury barometer
What is the difference between Mercury barometer and a aneroid barometer?
their spelling is different.
