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.

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.
