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.
What liquid is used in a barometre?
mecury
Is barometre used for cooking?
A barometre measures air pressure and is one of the tools to predict the weather; cooking uses a thermometer, which measures temperature.

How are the Mercury and aneroid barometers alike?

Who invented aneroid Barometer?
Lucien Vidie, French scientist, invented the aneroid barometer in 1843.
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 are the parts of an bp apparatus aneroid?
