When water is used as barometer liquid the height of the water column at sea level is 76 cm.

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

What is the relative density of liquid if the height of the water coloumn and the height of a liquid column in a Hare's apparatus are 20 cm and 40 cm, respectively ?

At a given place is barometer records a pressure of 70 cm of mercury. If the mercury in the barometer is replaced by water, what would be the height of the water column? Take density of mercury =13600kg//m^(3) density of water =1000kg//m^(3)

The liquid used in Barometer is:

The lower end of a glass capillary tube is dipped in water. Water rises to a height of 9 cm. The tube is then broken at a height of 5 cm. the height of the water column and angle of contact will be

Suppose water is used in a barometer instead of mercury. If the barometric pressure is 760 mm Hg , what is the height of the water column in the barometer at 0^(@) C . The densities of water and mercury at 0^(@) C are 0.99987 g cm^(-3) and 13.596 g cm^(-3) , respectively. Strategy : The prtessure exerted by a column of liquid h whose density is d is hdg . Because the pressure are equal , we can equate the expressions for water (W) and mercury (M): h_(W)d_(W)g = h_(M) d_(M)g or h_(W)d_(W) = h_(M)d_(M) Rearranging gives (h_(W))/(h_(M)) = (d_(M))/(d_(W)) This implies that the height of the liquid column in inversely proportional to its density . Solve the equation to find the height of the water column, h_(W) .

Why mercury is used in barometer instead of water ?

The lower end of a glass capillary tube is dipped in water. Water rises to a height of 9 cm. The tube is then broken at a height of 5 cm. The height of the water column and angle of contact will be
