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 pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.
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 in the space above mercury in a barometer?
The space above the mercury is airtight, there is no air above the mercury
Does a mercury barometer or aneroid barometer measure air pressure?
mercury has a sudden fall and then the barometter measure it and when i mean by fall i mean air pressure so yeah it's cool I knoe it doesn't make sense but Im just writing this anyway. Even though it's pure glorius silly you know what. I PUT THAT WORD BUT THEY WON'T LET ME POST THIS STUPID ANSWER
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.
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.
An increase in air pressure will cause the mercury in a barometer to?
An increase in air pressure will cause the mercury in a barometer to rise, indicating higher atmospheric pressure. This typically indicates fair weather conditions.
When air pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.

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.
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
Does air exert pressure on air or mercury?
Yes. (see - barometer)
What is in the space above mercury in a barometer?
The space above the mercury is airtight, there is no air above the mercury
Where the mercury barometer is used?
at sea level to messure air.
Why must there be a near vacuum in the tube of mercury barometer?
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
In a mercury barometer what is the height of the mercury for average air pressure?
2.5 feet or 760 milimeters
