CAPILLARY ACTION

CAPILLARY RISE

The upward movement of a liquid against

the force of gravity inside narrow spaces and thin

tubes is called capillary rise . This property of liquid

is called capillarity. A common apparatus used to

demonstrate capillarity is the capillary tube.

REASON

Capillarity occurs because of

intermolecular forces between the liquid and

surrounding solid surface. And due to the pressure

of cohesion and adhesion which cause the liquid

work against gravity.

CAPILLARY FALL

Liquids like mercury which have high

cohesive force show capillary fall inside such

glass tubes.

Page 8: power point presentation on capillary action

When the diameter of the tube

increases , capillary rise increases.

APPLICATIONS

Ordinary kerosene lamp

Softness of cotton

Hoeing of the soil before summer season

Capillary action draws ink to the tips of

fountain pen nibs.

Plants and trees getting water from earth.
