Illustrations of capillarity:

(i) A blotting paper absorbs ink by capillary action. The pores in the blotting paper act as capillaries.

(ii) The oil in a lamp rises up the wick through the narrow spaces between the threads of the wick.

(iii) A sponge retains water due to capillary action.

(iv) Walls get dumped in the rainy season due to absorption of water by bricks.

Capillary Pressure appears when two different and immiscible phases and a third solid material such as rock surface exist.
