In the Mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. Other liquids can be used in barometers, but mercury is the most common because of its great density.

∙ 13y agoIn the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. Other liquids can be used in barometers, but mercury is the most common because of its great density (13.6 g/cm3). With a mercury barometer the column of fluid is only 760 mm high at normal atmopheric pressure, with water (with a much lower density of 1 g/cm3) it would have to be almost 10 m tall.

Types of Barometers?
anaeriod barometer and a mercury barometer
What are 2 types of barometers?
Mercury and aneroid barometers.
What are barometers made of?
It consists of a thin tube containing mercury
Why is mercury not used in thermometers any more?
Mercury is not used in thermometers, because mercury is poisonous.
Why does the size of the cross-sectional area of a mercury barometer not affect the height of the enclose mercury column?
The height of the column in a mercury barometer is determined by pressure, not force. Fluid pressures depend on density and depth-pressure at the bottom of a wide column of mercury is no different than the pressure at the bottom of a narrow column of mercury of the same depth. The weight of fluid per area of contact is the same for each. Likewise with the surrounding air. Therefore barometers made with wide barometer tubes show the same height as barometers with narrow tubes of mercury.
What element is used for barometers?

Why are barometers often more practical than mercury barometers?
They are more portable and can be used for airplane equipment
How is mercury used in the modern world today?
Mercury is used in thermometers barometers and flourescent lightbulbs.
What are 2 types of barometers?

Does barometers contain Mercury?
Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any mercury.
What is Mercury used in?
Mercury was commonly used in thermometers and barometers. However, because it is poisonous, people are trying to use it in less things now.
