What is capilary reaction?

Capillary reaction refers to the movement of liquids within narrow spaces or porous materials, driven by surface tension, cohesion, and adhesion. This phenomenon is commonly observed in capillary tubes, where liquids can rise or fall against gravity. It plays a crucial role in various natural processes, such as the movement of water and nutrients in plants through their xylem. Additionally, capillary action is significant in various industrial applications, including ink delivery in pens and the absorption of liquids in sponges.
