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 measures a barometer with Mercury?
Maybe you mean what does a mercury barometer measure. In which case the answer is atmospheric pressure.
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
When air pressuer increases what does the mercury in the barometer do?
Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.
How does a barometer work?
There are a couple of types. By far the most common is the aneroid barometer. The heart of an aneroid barometer is a sealed can. As the surrounding pressure rises and falls, the can shrinks and expands. A mechanical linkage translates the deflection into the movement of a dial. It could also be measured with a strain gauge, with the resistance translated into pressure.The Mercury barometer has a tube sealed at the top, full of mercury sitting in a cup full of mercury. A vacuum forms at the top because the exterior pressure can only support a column equal to the height times the density of mercury.Air pressure pushes on the mercury inside of the container, the mercury moves up the glass tube. The greater the air pressure the higher the mercury will rise.
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
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 a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
When air pressure goes up the liquid in a mercury barometer goes?
rises
Where the mercury barometer is used?
at sea level to messure air.
What is a barometer with Mercury called?
A mercury barometer.
Types of Barometers?
anaeriod barometer and a mercury barometer
What is a mercury barometer used for?
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
When climbing a mountain with a barometer will the mercury level decrease or increase?
decrease
What are the Precautions for aneroid and mercury barometer?
Mercury barometer precaution
An aneroid barometer is different from a mercury barometer in that it does not contain?
Mercury
What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
