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.

How a barometer can be used to measure the vapor pressure of a liquid?

A mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.


What liquid metal is found inside of a barometer?

Mercury.


What kind of liquid is found in a barometer?

Mercury is the liquid typically found in a barometer. It is used to measure atmospheric pressure due to its density and ability to rise and fall within the tube as pressure changes.


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 liquid in a termometer?

Actually a barometer can be made of just about any liquid with a sufficiently low vapour pressure. For example, most people don't realize that their toilet acts as a barometer. Traditionally barometers were made with Hg, but they could be made with just about any liquid with a low VP.

How did the barometer get its name?

The barometer got its name from a combination of two Greek words: "baros" meaning weight, and "metron" meaning measure. This reflects its function of measuring atmospheric pressure by the weight of the air.


When air pressure goes up the liquid in a mercury barometer goes?

When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
