The Italian scientist Evangelista Torricelli is considered the inventor of a barometer in 1643 but many others have been preoccupied with this issue and before it.
The purpose of a barometer is to measure the pressure.
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.
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.
When air pressure increases, the mercury in a barometer rises.
The level of mercury in a barometer rises when atmospheric pressure increases. This occurs when the weight of the air above the barometer pushes down more forcefully, causing the mercury to be pushed up into the tube. Conversely, when atmospheric pressure decreases, the mercury level falls. Thus, changes in weather patterns often influence the mercury level in a barometer.
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.
A mercury barometer.
barometer has mercury inside it .
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. (:
A Mercury barometer is used to measure atmospheric pressure.
people were suffering a lot so barometer was discovered
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.
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.
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.

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 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.
