The tube of mercury barometer is 4mm in diameter. How much error does the surface tension cause in the reading? Surface tension of mercury = `540" x "10^(-3) Nm^(-1)`, angle of contact = `135^(@)`. Density of mercury `= 13.6 xx 10^(3)kg m^(-3)`.

The tube of mercury barometer is 4mm in diameter. How much error does the surface tension cause in the reading? Surface tension of mercury = 540" cc "10^(-3) Nm^(-1) , angle of contact = 135^(@) . Density of mercury = 13.6 xx 10^(33)kg m^(-3) .

The diameter of the mercury barometer tube is recorded as 6 mm. How much error is introduced due to surface tension in this reading. Surface tension of mercury is 540 xx 10^(-3)" N/m" Angle of contact for mercury is 140^@ .

Calculate the diameter of a capillary tube in which mercury is derpessed by 1.21 cm. Given surface tension for mercury is 540 xx 10^(-3) "Nm"^(-1). the angle of contact with glass is 140^(@) and density of mercury is 13.6 xx 10^(3) "kg" m^(-3).

The tube of a mercury barometer is 1 cm is diameter. What correction dur to capillarity is to be applied to the barometric reading if the surface tension of mercury is 435.5 dyn/cm and the angle of contact of mercury with glass is 140^(@) ?

What is the excess pressure inside a drop of mercury of radius 3.0 mm? (Surface tension of mercury is 4.65 xx 10^(-1) N m^(-1) )

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

Mercury has an angle of contact equal to 140^(@) with soda lime galss. A narrow tube of radius 1.00mm made of this glass is dipped in a through containing mercury. By what amount does the mercury dip down in the tube relative to the mercury surface outside? Surface tension of mercury at the temperature of the experiment is 0.465 Nm^(-1) . Density of mercury = 13.6xx10^(3) kg m^(-3) .

Water rises up in a glass capillary upto a heigh 10 cm, while mercury falls down by 3.5 cm in the same capillary. If the angles of contact for water-glass and mercury-glass are taken as 0^(@) and 135^(@) respectively, compare the surface tensions of water and mercury. [Given density of water = 10^(3) kg m^(-3) , density of mercury = 13.6 xx 10^(3) kg m^(-3) ]
