What are the Precautions for aneroid and mercury barometer?
Mercury barometer precaution
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.
When climbing a mountain with a barometer will the mercury level decrease or increase?
decrease
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
What are the difference between the mercury barometer and aneroid barometer?
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
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.
An increase in air pressure will cause the mercury in a barometer to?
When you increase air pressure the mercury in a barometer will rise. Conversely when air pressure decreases the mercury in a barometer will drop.
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.
