capillary rise

Capillary rise is the phenomenon where a liquid spontaneously rises in a narrow tube or porous material against gravity, driven by adhesive and cohesive forces. This tag covers discussions of capillary action, including its demonstration in educational contexts such as the Royal Institution Christmas Lecture 2010. The topic relates to fluid dynamics and surface tension, with applications in science and engineering. On WindowsForum, users may explore capillary rise in the context of physics, material science, or general curiosity about natural phenomena.
