A liquid film at the surface behaves as a

The angle of contact for a liquid which wets the surface of a solid is

A liquid dies not wet the surface of a solid, the angle of contact is

F_c and F_A denote cohesive and adhesive forces on a liquid molecule near the surface of a solid. The surface of liquid is convex , if

The graph is drawn between the applied force F and the strain (X) for a thin uniform wire. The wire behaves as a viscous liquid is

If n drops of a liquid , each with surface energy E , join to form a single drop , then

The brilliant colours of soap bubbles and thin oil films on the surface of water are due to

A ring of radius r, and weight W is lying on a liquid surface. If the surface tension of the liquid is T, then the minimum foce required to be applied in order to lift the ring up

The velocity of efflux of liquid through orifice is equal to velocity which a body attains while falling freely from the free surface of liquid to the orifice. This is known as "_______".

A film of soap solution is formed in a rectnagular wire frame of length 10 cm and breadth 5 cm . The surface energy of the film , if the surface tension of soap solution is 0.035 N/m is

The total energy of the free surface of a liquid drop is 2 pi times the surface tension of the liquid. What is the diameter of the drop ?
