A capillary tube is dipped in a liquid. If the levels of liquid inside and outside the tube are same then the angle of contact is

When a mercury drop of radius R, breaks into ‘n’ droplet of equal size, the radius (r) of each droplet is:

A frame made of metallic wire enclosing a surface area is covered with a soap film. If the area of the frame of metallic wire is reduced by 50%, the energy of the soap film will be changed by

A number of droplets, each of radius ‘r’ combine to form a drop of radius ‘R’. If ‘T” is the surface tension, the rise in temperature will be:(Assume that the energy evolved is converted into heat)

If the work done in blowing a bubble of volume V is W then the work done in blowing a soap bubble of volume 2V will be

The excess pressure inside a spherical drop of radius of a liquid of surface tension Tis

Two mercury drop (each of radius r) merge to form a bigger drop. If T is the surface tension, the surface energy of biggest drop is

If a drop of water is broken in to smaller drops the surface energy

On the surface of the liquid in equilibrium, molecules of the liquid possess

When a glass capillary tube of radius 0.015 cm is dipped in water, the water rises to height of 15 cm within it. Assuming contact angle between water and glass to be 0°, the surface tension of water is [Pwater 1000 kg m-³, g= water 9.81 ms-¹
