When a drop of water is dropped on oil surface, then

Two pieces of glass plate one upon the other with a little water in between them cannot be separated easily because of

The potential energy of a molecule on the surface of liquid compared to one inside the liquid is

If T is the surface tension of soap solution, the amount of work done in blowing a soap bubble from a diameter D to 2D is

If two soap bubbles of equal radii r coalesce then the radius of curvature of interface between two bubbles will be

What is ratio of surface energy of 1 small drop and 1 large drop, if 1000 small drops combined to form 1 large drop?

The amount of work done in forming a soap film of size 10 cm × 10 cm is (Surface tension T = 3 × 10^–2 N/m )

A liquid drop of diameter D breaks upto into 27 small drops of equal size. If the surface tension of the liquid is σ, then change in surface energy is

One thousand small water drops of equal radius combine to form a big drop. The ratio of final surface energy to the total initial surface energy is

If the radius of a spherical liquid (of surface tension S) drop increases from r to r + ∆r, the corresponding increase in the surface energy is
