Due to the presence of certain impurities in mercury, its effective density is `12 g cm^(-3)`. What is the barometer reading at sea level ?

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.

Density of mercury is 13.6 g cm^(-3) . Its density in kg m^(-3) is

When a mercury barometer is taken to a place at a height of 25 m above the sea level it shows a pressure difference of 2.5mm with respect to the pressure at the surface of the sea. If the relative density of mercury is 13.6, find the average density of air near sea level

The mass of copper metal is 6.342 g and the density of copper is 7.6 g//cm^(3) . What is its volume ?

One third of a cylinder of 3 m height is filled with oil of density 0.62 g cm ""^(-3) . and the rest of it is filled with mercury of density 13.6 g cm ""^(-3) . Calculate the total pressure at the bottom of cylinder due to both oil and mercury.

Two bodies are in equilibrium when suspended in water from the arm of a balance. The mass of one body is 60 g and its density is "12 g cm"^(-3) . If the mass of the other body is 72 g, its density in g "cm"^(-3) is

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure at the air temperature=1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

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?

A barometer tube contains a mixture of air and saturated water vopour in the space above the mercury column. It reads 70cm when the actual atmospheric pressure is 76cm of mercury. The saturation vapour pressure at roon tempature is1.0 cm of mercury, The tube is now lowered in the reservoir till the space above the mercury cloumn is reduced to half its origina volume. Find the reading of the barometer. Assume that the temperature remains constant.
