The pressure given by a mercury barometer is always less than actual pressure. Why?

A barometer is constructed with its tube having radius 1.0 mm. Assume that the surface of mercury in the tube is spherical in shape. If the atmospheric pressure is equal to 76 cm of mercury, what will be the height raised in the barometer tube? The contact angle of mercury with glass 135^@ and surface tension of mercury =0.466Nm^-1 . Density of mercury =13600kgm^-3 .

Why mercury is used in barometer for measuring atmospheric pressure?

The height of mercury barometer is h when the atmospheic pressure is 10^(5)Pa . The pressure at x in the shown diagram is

How will you show that there is vacuum above the surface of mercury in a barometer ? What name is given to this vacuum ?

The atmospheric pressure at earth surface is P_(1) and inside a mine is P_(2) . They are related as :

The vertical height of mercury in a simple barometer is dependant on the area of cross-section of barometer tube.

The depression of mercury in a capillary tube of radius R_(1) is observed to be equal to the rise of water in another capillary tube of radius R_(2) . If the ratio of surface tension of mercury and water is 7.5 , ratio of their density (p_(Hg))/(p_("water"))=13.6 and their angle of contact are theta_(Hg)=135^(@) and theta_("water")=0^(@) in the respective tubes then R_(1)//R_(2) is :

Express one atm pressure in terms of the height of mercury column.

Explain why does the mercury level in a barometer go down when atmospheric pressure decreases?
