Write the $$10$$ uses of mercury barometer.
A mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. Mercury Barometers are used for:-
$$1.$$ Measurement of atmospheric pressure
$$2.$$ Determining the altitude of a place
$$3.$$ Weather Forecasting
$$4.$$ Calibration and checking of aneroid barometers
$$5.$$ Application in Fluid Mechanics
$$6.$$ Measurement of pressure in aircrafts
$$7.$$ Surface Weather Analysis
$$8.$$ Preparation of Barographs
$$9.$$ Usage in Physical sciences like Physics, Astronomy & Chemistry
$$10.$$ Preparation of aircraft altimeters
