What measures a barometer with Mercury?
Maybe you mean what does a mercury barometer measure. In which case the answer is atmospheric pressure.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
When air pressuer increases what does the mercury in the barometer do?
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.
What is in the space above mercury in a barometer?
The space above the mercury is airtight, there is no air above the mercury
What deos a barometer measure?
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
What is a barometer with Mercury called?
A mercury barometer.
Types of Barometers?
anaeriod barometer and a mercury barometer
What are the Precautions for aneroid and mercury barometer?
Mercury barometer precaution
An aneroid barometer is different from a mercury barometer in that it does not contain?
Mercury
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 does a barometer has in it?
barometer has mercury inside it .
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.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
What measures a barometer with Mercury?
Maybe you mean what does a mercury barometer measure. In which case the answer is atmospheric 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.
Torricelli invented a device for measuring air pressure called a(n)?
To measure the local pressure of the Earth's atmosphere, Torricelli invented the first Mercury Barometer.
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.
