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 is in a thermometer and a barometer?
A thermometer measures temperature - most are now electric but they used to have alcohol or mercury in them. A barometer measures air pressure - they are now electric but used to have air in them (in a bellows with a spring).
What is the instrument that measures air pressure without using liquid?
An aneroid barometer is a type of instrument that can measure air pressure without using liquid. It consists of a small, flexible metal box that is partially evacuated and attached to a mechanical linkage that can record changes in atmospheric pressure.
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.
In a homemade barometer why did the straw move up and down?
The straw moved up and down in a homemade barometer due to changes in atmospheric pressure. When the pressure increased, the liquid in the bottle pushed the straw up. When the pressure decreased, the straw moved down due to the weight of the atmosphere pressing down on the liquid in the bottle.
What is the definition of aneroid?
Containing no liquid; -- said of a kind of barometer., An aneroid barometer.
What liquid metal is found inside of a barometer?
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.
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.
Instrument that measures air pressure without using a liquid?
aneroid 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 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.
Which liquid is used in an aneroid barometer a mercury b alcohol c none?
mercury
What is the name of barometer which does not contain liquid?

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.
What kind of liquid is gas?
Gasoline is a nonpolar organic liquid. It is a mixture of a large number of organic substances found in crude oil.
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.
