#snsinstitutions #snsdesignthinkers #designthinking • Capillary rise • When a liquid's surface rises in a tube, it's called capillary rise. This happens when the adhesive force between the liquid and the tube's walls is stronger than the liquid's cohesive forces. For example, water in a thin glass tube exhibits capillary rise. • Capillary depression • When a liquid's surface falls in a tube, it's called capillary depression. This happens when the liquid's cohesive forces are stronger than the adhesive force between the liquid and the tube's walls. For example, mercury in a thin glass tube exhibits capillary depression.
