Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
If the atmospheric pressure is 24.9 inches what is the pressure in mm Hg?
18,920 mm of mercury at 24.9 ATM
What instruments are used to measure the atmospheric pressure?
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
How do fortin barometers work?
The way the Fortin barometer works is different in a sense that it uses atmospheric pressure to balance the weight of a column of mercury against it. From that, any change in the atmospheric pressure is accompanied by an immediate change in the level of the mercury and can be measured against the scale engraved on the barometer.
If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
Expressed in mm of mercury?
Pressure, in particular atmospheric pressure.
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
What do mercury barometer measure?
It measure the Atmospheric Pressure.
What the perssure on the planet mercury?
The atmospheric pressure is negligible.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
To measure pressure above atmospheric pressure you would use a?
mercury manometer
Define thin atmosphere relating to mercury?
It is so thin that the atmospheric pressure is one half of a millionth of the earth's atmospheric pressure.
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
What does a mercury barometer measures?
Barometers are used to measure pressure.
What measures a barometer with Mercury?
Maybe you mean what does a mercury barometer measure. In which case the answer is atmospheric pressure.
