Answer 2

Explanation:

the atmospheric pressure is generally expressed in terms of the height of mercury column.at normal temprature and pressure, the barometric height is 760mm at sea level which is taken as one atmosphere. thus atmospheric pressure is also expressed in a unit atmosphere where 1 atm= 0.76m of hg. 9.
