Capillary Action

I might wanna share something that i know what really really really is. I know my self not knowing as much as other people does, but one thing for really f***ing sure. This is the phenomena that we called and named it Cappilary Action.

Capillary action is the result of adhesion and surface tension. Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact, so instead of just the edges moving upward, the whole liquid surface is dragged upward.

Capillary Action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube is limited by surface tension. Acting around the circumference.
