Answer»

Surface tension is the energy required to increase the surface area of a liquid by a unit amount

.Molecules in the interior experience an attractive force from neighboring molecules which surround on all sides

Molecules on the surface have neighboring molecules only on one side (the side facing the interior) and thus experience an attractive force which tends to pull them into the interior

The surface of the liquid will rearrange until the least number of molecules are present on the surface

.The surface molecules will pack somewhat closer together than the rest of the molecules in the liquid
