What is capillalirity?

Answer 1

Capillarity, also known as capillary action, is the ability of a liquid to flow in narrow spaces without the assistance of external forces, such as gravity. This phenomenon occurs due to the adhesive forces between the liquid and the surrounding solid surfaces, as well as the cohesive forces within the liquid itself. It is commonly observed in materials like soil, where water can move upward through tiny pores, and in thin tubes, where liquids can rise against gravity. Capillarity plays a crucial role in various biological and physical processes, including the movement of water in plants.
