What does a decrease in the height of a column in a mercury barometer mean?
air pressure is decreasing
What is the height of a column of water where the pressure at the bottom of the column is 20.0 lb inch squared?
It is approx 46.3 feet.
What relation between pressure and height?
Pressure decreases as height increases and vice-versa.
What is the approximate height of Moroles' sculpture Spirit Inner Column 1?

How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb What is the formula?
Formulas for atmospheric pressure variation with altitude. Scroll down to related links and look at "Atmospheric pressure - Wikipedia".
As air pressure increases does the height of a column of mercury in a barometer increase?
Yes, as air pressure increases, the height of the column of mercury in a barometer also increases. This is because the higher air pressure pushes down on the mercury in the barometer, causing the column to rise. Conversely, lower air pressure will cause the column of mercury to fall.
What does a decrease in the height of a column in a mercury barometer mean?
air pressure is decreasing
What would happen to a mercury barometer when the air pressure is getting lower?
The height of the column of mercury would be lower.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
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.
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.
What is 165 mm hg?
It is a measure of pressure exerted by a column of mercury which is 165 mm in height.
A glass column is filled with mercury and inverted in a pool of mercuryThe mercury column stabilizes at a height of 735 mm above the pool of mercuryWhat is the pressure of the atmosphere?
1.034013605
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.
When air pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.
Why is the value of atmospheric pressure compared to mercury?
Atmospheric pressure will support a column of mercury to about 760 mm. Mercurial air pressure is described as '760 mmHg'. As air pressure changes , the height of this column will also change. If you did it with water, the column would have to be about 34 feet (10.2 metres) in height.
What weather will accompany a decrease in the height of the mercury column in a mercury barometer?
the atmospere can not support the greater height column and the column of mercury will drop to the level in which the atmospere can support
