Pintajännitteitä
Pintajännitteitä, often translated as surface tension, is a property of liquids that causes the surface of the liquid to behave like a stretched elastic membrane. This phenomenon arises from the cohesive forces between liquid molecules. Within the bulk of the liquid, molecules are attracted equally in all directions. However, at the surface, molecules are attracted more strongly by the molecules below and beside them than by the air or gas above. This unbalanced inward pull causes the surface molecules to be packed more tightly and results in a net inward force.
This inward force leads to several observable effects. For instance, it allows small insects like water striders
