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 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.
You carry a barometer with you to the top of a very tall buildingyou notice that the barometer reading goes down as you ride up to the107th floorexplain what happened and why?
Barometer's measure air pressure and the Earth's air pressure at a certain place is due to the weight of the air above it. So the higher you go the air pressure drops because there is less air above you pushing down with its weight.
Which weather instrument is use to measure air pressure?
The barometer is the instrument that is used to measure the air pressure.
Can humidity effect the reading of a barometer?
No , a Barometer measures air pressure.
What a barometer with Mercury?

When the barometer reading goes upwe have a pressure area?
air pressure
When air pressure goes up the liquid in a mercury barometer goes?

What is an example sentence for the word barometer?
The barometer shows low air pressure in a hurricane.My pain increases when the barometer drops below 29.8 to 30.A barometer gives a reading of air 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 is a barometers?
A barometer is a device used to measure atmospheric pressure. If pressure is high (good weather), then pressure on the barometer will exceed 1000 millibars. If the pressure is low (bad weather), then the pressure reading on the barometer will be below 1000 millibars.
How can you determine air pressure?
Air pressure is usually measured using a barometer. This device usually has mercury inside it along a tube that is a compete vacuum. As the air pressure rises the pressure of the air pushes down on the mercury and forces it to rise further into the vacuum. 760 mm of mercury is considered to be 1 atmosphere. For very high pressures an aneroid barometer is used. This has wafers inside that are compressed under high pressure that give a reading.
What You Get From aneriod barometer?
A reading of the air pressure. It's handy for rough weather predictions.
A barometer is an instrument used for measuring water pressure?
