What is a device for measuring atmostpheric pressure?
The most usual devices are barographs and barometers. A barometer can work off an aneroid cell (eg digital aneroid barometer) or a column of mercury (eg Kew Pattern barometer). Barographs usually work off aneroid cells and through a linkage system print the pressure onto a chart (usually changed weekly although there are daily barometers as well). So the main difference is that a barometer gives a spot reading while the barograph is continuous, although it's possible for the readings from a digital barometer like one connected to an Automatic Weather Station to be saved and called up later, or even printed out in graph form. The usual unit for air pressure in meteorological circles is the hectoPascal (hPa) which replaced the millibar some years ago (the units have the same numerical value, though) except for the US which sticks with the old inches of mercury (InHg).
What two units are commonly used to measure air pressure?
Probably a mercury barometer and a aneroid barometer. -adrian
Which liquid is used in an aneroid barometer a mercury b alcohol c none?
mercury
What is an aneroid barometer called?
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
What is the difference between the aneroid barometer and a mercury barometer?
An aneroid barometer measures air pressure using a flexible metal box called an aneroid cell, whereas a mercury barometer uses a column of mercury to measure air pressure. Aneroid barometers are more portable and do not use toxic mercury like mercury barometers.
Which statement accurately describes a difference between a mercury barometer and an aneroid barometer?
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
Why partially evacuated chamber is used in aneroid barometre?
A partially evacuated chamber is used in an aneroid barometer because changes in atmospheric pressure will cause the flexible chamber to expand or contract, which is then measured and indicated on the barometer dial. This mechanism allows the aneroid barometer to measure variations in air pressure without the need for a liquid-filled chamber like in a traditional mercury barometer.
How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
What is the difference between Mercury barometer and a aneroid barometer?
their spelling is different.
Does a aneroid barometer use alcohol?
No, an aneroid barometer does not use alcohol. It measures atmospheric pressure using a small, flexible metal box called an aneroid cell, which expands or contracts with changes in pressure. This movement is then converted into a reading on the barometer.
Who invented aneroid Barometer?
Lucien Vidie, French scientist, invented the aneroid barometer in 1843.
What kind of barometer measures air pressure by using a metal chamber that is sensitive to pressure changes?
The kind of barometer you are referring to is a aneroid barometer. It uses a metal chamber (an aneroid cell) which expands or contracts with changes in air pressure. This movement is then converted into a reading of air pressure on a dial.
An aneroid barometer is different from a mercury barometer in that it does not contain?
An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.
What is the name of barometer which does not contain liquid?
It's known as an aneroid barometer. It works by the difference in pressure causing a partially flattened tube which is wound into a coil to straighten out. The movement is converted to circular motion by a series of gears. the central shaft has a needle attached which indicates the pressure.
What tool is used for measuring air pressure?
A barometer is the tool used for measuring air pressure. It can be either an aneroid or mercury barometer.
