Explain shape of liquid drops.

Explain the shape of liquid drops on a solid surface with the help of diagram.

When there are no external forces, the shape of a liquid drop is determined by

Explain the fall of liquid in the capillary an the basis of pressure difference.

Explain the rise of liquid in the capillary on the basis of pressure difference.

Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression?

Explain excess of pressure inside a liquid drop.

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 ?

Derive an expression for excess pressure inside a liquid drop.

A spherical liquid drop is placed on a horizontal plane . A small distrubance cause the volume of the drop to oscillate . The time period oscillation (T) of the liquid drop depends on radius (r) of the drop , density (rho) and surface tension tension (S) of the liquid. Which amount the following will be be a possible expression for T (where k is a dimensionless constant)?

Explain, why an organic liquid vapourises at a temperature below its boiling point in its steam distillation?
