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

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

The rise of a liquid in a capillary is due to

Explain shape of liquid drops.

Rise of liquid in a thin capillary tube depends upon

Explain the capillary action .

The level of liquid in a capillary tube is plane, because

Explain the cause of capillary action in a capillary tube.

Explain the classification of polymers on the basis of structure.

When a capillary tube of radius 'r' is dipped vertically in a liquid of surface tension T, the liquid rises to a height 'h' in the tube above the level outside the tube. If the angle of contact is theta , the density of the liquid is rho , then the pressure difference is.

Draw a neat labelled diagram of rise of liquid in capillary tube showing different components of tension (force).
