Torricelli's barometer used mercury. Pascal duplicated it using French wine of density `984 kg m^(-3)`. Determine the height of the wine column for normal atmospheric pressure.

Torricelli's barometer used mercury but pascal duplicated it using French wine of density 984 kg m^(-3) . In that case, the height of the wine column for normal atmospheric pressure is (Take the density of mercury =1.36xx10^(3) kg m^(-3) )

Why mercury is used in barometer for measuring atmospheric pressure?

The 10% of total volume of the barometer liquid (mercury) contains impurities having an average density 5 g cm^(-3) . When this faulty barometer is used to measure the atmospheric pressure it reads 80 cm of the liquid column. Determine the correct atmospheric pressure.

If water is used instead of mercury in a barometer, what will be the height of water column?

If water be used to construct a barometer, what would be the height of water column at a standard atmospheric presure (76cm of mercury)?

1 atmospheric pressure is taken as the pressure exerted by a mercury column of height 76 cm . Wh at is the approximate height of an air column that will produce one atmospheric pressure on its bottom ? [Assume that the temperature and density of a ir and th e value ofg remains constant throughout the a ir column .] [rho_("mercury")=13.6xx10^3kg//m^3 and rho_("air")=1.3kg//m^3 ]
