Surface tension          03/20/16
Do you ever wonder why a liquid is able to maintain it’s volume and incompressibility? This facet is due to a phenomena known as surface tension. Because molecules of the same element are under the influence of the same intermolecular forces, they tend to coalesce together. This means that there is a net inward force on the molecules due to the fact that there is no molecules on the outside of the surface area to interact with. In fact, when liquids are in an environment with little to no external forces, they end up becoming spherical shaped as a result surface tension.
