A Mercury barometer consists of a tall glass tube filled with mercury inverted into a container of mercury. The mercury in the tube will fall until the weight of the mercury column is balanced by the atmospheric pressure pushing down on the surface of the mercury in the container. The measurement is then taken from the height of the mercury column in the tube.

What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
Which statement accurately describes a difference between a mercury barometer and an aneroid barometer?
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
An aneroid barometer is different from a mercury barometer in that it does not contain?
An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.
Types of Barometers?
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.
When you measure air pressure most accurately you should use a mercury?
barometer. Mercury barometers are very accurate instruments for measuring air pressure because the height of the mercury column is directly proportional to atmospheric pressure. Mercury is a dense liquid, making slight changes in pressure more visible in the barometer.
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 first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
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?
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
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?

What is the difference between Mercury barometer and a aneroid barometer?
their spelling is different.
