What happens when the mercury in barometer or manometer is replaced by water or any other less dense liquid than water?
Since water is lighter than Mercury, this means the height will differ. The denser (high relative density) the fluid, the shorter the height. If the fuild is light such as water its height will be much higher than that of mercury. Also, the denser the material is the higher the pressure.

What is an open arm manometer?
It is a type of manometer, an object used to measure the pressure of different things, and the open armed manometer allows for the atmospheric pressure in the tube of the manometer. So the sample gas pressure pushes on the mercury that is already being pushed on by the atmospheric pressure. Then you add the atmospheric pressure to the change in the mercury (in mm) and that gives you your pressure. It's like a tire gauge.
How are mercury and an aneroid barometer alike?
Mercury and an aneroid barometer are both used to measure atmospheric pressure. However, mercury barometers use a column of mercury to measure pressure changes, while aneroid barometers use a flexible metal box to make pressure readings. Both devices are used to forecast weather patterns.
What is barometric pressure measured by?
A barometer measures atmospheric pressure to determine weather or altitude changes.
What occupies the space above the mercury column in the barmoter's glass tube?
In a barometer, the space above the mercury column is typically a vacuum. This allows the mercury column to accurately reflect changes in atmospheric pressure without any interference from air molecules or other gases.
If a barometer reads 535 mm Hg what is the atmospheric pressure expressed in centimeters of mercury?
mmHg represents the height of a column of mercury (Hg) in millimeters (mm) (as opposed to inches of mercury (inHg)). Since there are 10 mm (millimeters) in a centimeter, simply divide the mmHg by 10 and you find that 535mmHg is 53.5 centimeters Hg (cHg?).
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
What is a barometer with Mercury called?
A mercury barometer.
What does a barometer has in it?
barometer has mercury inside it .
What happen when mercury used in inverted manometer?
When mercury is used a manometer fluid and the manometer tube is inverted it will measure the small pressure difference in liquids. This is a tool used by scientists.
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.
How do you use thermometer in a sentence?
The pressure of the gas within the test chamber is measured by an external manometer. In tests of submarine designs, pressure readings on a manometer are compared with those of the stress gauges on the hull plates.
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.
Who invented the mercury manometer?
The mercury manometer was invented by Evangelista Torricelli in 1643. Torricelli was an Italian physicist and mathematician who discovered that the height of a column of mercury in a tube varied with atmospheric pressure, leading to the creation of the mercury manometer for measuring pressure.
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.
