Introduction to Capillary Action

Capillary action is a fascinating physical phenomenon where liquids rise or fall in a narrow tube or a porous material, defying gravity. This action results from the interplay of two forces: adhesion (the attraction between the liquid and the surface of the material) and cohesion (the attraction between the liquid molecules themselves). It’s a critical concept in various scientific and engineering fields, from biology to material science.
