How is barometer used
Web3 feb. 2024 · Answer: A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. For pressure, the SI system’s basic unit is Pascal (Pa), which is N/m² (Newton per square meter, while Newton is kgm/s²). WebBarometer is used to measure air pressure and the pressure tendency can forecast short term changes in the weather. Again, mercury is also the only metal which is in liquid state at room temperature. It has a high coefficient of expansion and hence we can also use it as thermometric fluid .
