Capillarity is the phenomenon where liquids rise in narrow tubes or cracks against gravity. This occurs due to adhesion between the liquid and tube molecules. Examples include foundation pens writing on paper and water absorption in plants. Capillary rise decreases with increasing tube diameter and is caused by adhesion between the liquid and material of the container.

4. The rising of liquids through
narrow tubes and small cracks against
the gravitational force is termed as
capillary rise. This characteristic of a
liquid is known as capillarity

5. Examples
• Foundation pens can be
used to write on a paper.
• Chalk lamp experiment
• The absorption of water
molecules is plants.

6. ANOTHER EXAMPLES

7. CONCLUSION
• When the diameter of the tube
increases, the capillary rise
decreases.
• The capillary rise is due to the
adhesion between the molecule
of the material of the tube and
the liquid molecules.
