What is the barometric height of a liquid of density 3.4 g `cm^(-3)` at a place, where that for mercury barometer is 70 cm?

The barometric height at a certain place is 0.75 m of mercury. What will be the barometric height ifa liquid of density 3.4xx 10^3kg/m^3 is used to llll the barometric tube? [P_("mercury")=13.6xx10^3kg//m^3 ]

Calculate the total pressrue inside a spherical air bubble of radius 0.1mm at a depth of 10 cm below the surface of a liquid of density 1.1 g "cm"^(-3) and surface tension 50"dyne"" "cm^(-1). Height of Hg barometer =76"cm".

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.

Each side of an iron cube is 5 cm. This cube floats on mercury. What height of the cube remains above the surface of mercury? To cover the cube, if water is poured over mercury, then what will be the height of the water column? The density of iron is 7.2g*cm^(-3) and the density of mercury is 13.6g*cm^(-3) .

How is the barometric height of a simple barometer affected if Its tube is pushed down into the trough of mercury?

The density of liquid gallium at 30^(@)C is 6.095 g/mL. Because of its wide liquid range (30 to 2400^(@)C ), gallium is used as a barometer fluid at high temperature. What height (in cm) of gallium will be observed on a day when the mercury barometer reads 740 torr? (The density of mercury is 13.6 g/mL.)
