Solution

The correct option is A more
Mercury has a higher surface tension than water. This can be seen when looked at a drop of water and a drop of Mercury. The greater the surface tension of the liquid, the higher the bead of liquid will bow over. Surface tension is due to the different forces experienced by molecules in the interior of a liquid and those on the surface.

Q. Mercury has an angle of contact equal to

140^{o}

with soda lime glass. A narrow tube of radius 1 mm made of this glass is dipped in a trough containing mercury. The surface tension of mercury at the temperature of the experiment is

Q. Water rises to a height of

10 cm

in a certain capillary tube. Another identical tube when dipped in mercury, the level of mercury is depressed by

3.42 cm

. Density of mercury is

13.6 {gm/cm}^{3}

. The angle of contact for water in contact with glass is

0^{\circ}

and mercury in contact with glass is

135^{\circ}

. Then the ratio of surface tension of water to that of mercury is:
(use

\frac{0.0342}{\sqrt{2}} = 0.024

)

Q. 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 = 0.465 N m⁻¹. Density of mercury = 13600 kg m⁻³.
