Blotting paper consist of tiny capillaries and due to cohesion and adhesin forces the ink rises up.

Blotting paper is thick soft paper that you use for soaking up and drying ink on a piece of paper. So It has many capillarity tube by which ink may be absorb in piece of paper.

Capillary action, or capillarity, is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper, in some non-porous materials such as liquified carbon fiber, or in a cell. It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension

Why it is not diffusion phenomenon?

I think it is the capillary phenomenon.

Transfer of liquid from high concentration to low concentration. Ex: plants absorb water from ground by this phenomenon.

It is diffusion of ink through the blotting.

Mounica said:   1 decade ago
I surely think that diffusion of ink through blotting paper due to the phenomena of diffusion.

Tapash said:   1 decade ago
I think it should be diffusion of ink through the blotting.

Blotting paper provide a capillary tube for ink so ink fill in capillary tube and absorbed by blotting paper continuously.
