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.
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.
An aneroid barometer measures air pressure using a flexible metal box called an aneroid cell, whereas a mercury barometer uses a column of mercury to measure air pressure. Aneroid barometers are more portable and do not use toxic mercury like mercury barometers.
barometer has mercury inside it .
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
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.
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.
a barometer... and it is invented by torricelli..
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.
The device that Torricelli invented for measuring air pressure is called a barometer. It works by balancing the weight of the atmosphere with the weight of a column of mercury in a glass tube.
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.
