Barometer measures atmospheric pressure,while manometer measures the pressure of a gas in a closed system.

Vedclass · Answer

(B) barometer is an instrument used to measure atmospheric pressure. $A$ manometer is an instrument used to measure the pressure of a gas in a closed container. Example: If the atmospheric pressure (barometer reading) is $740 \ mm \ Hg$ and the difference in height between the two ends of a manometer is $2.1 \ cm$,the pressure of the gas can be calculated as: Pressure of gas = Atmospheric pressure - Difference in height $= 740 \ mm \ Hg - (2.1 \ cm 	imes 10 \ mm/cm)$ $= 740 \ mm \ Hg - 21 \ mm \ Hg$ $= 719 \ mm \ Hg$
