Explain why
Surface tension of a liquid is independent of the area of the surface.

Define surface tension.

How does the surface tension of a liquid vary with temperature?

How does surface tension of liquid vary with temperature?

A body is just floating on the surface of a liquid. The density of the body is same as that of the liquid. The body is slightly pushed down. What will happen to the body ?

Write the expression for electric flux passing through a surface in the electric field in terms of electric intensity of the field and area of the surface.

Give the expression for surface tension of a liquid in a capillary tube.
