Apply: properties of liquids

Liquids exhibit visible properties that provide information about the interactions occurring at the molecular level.

Surface tension is a force that reduces the surface area of a liquid. A substance with a high surface tension has a minimized surface area because molecules at the surface are pulled inward, resulting in a more spherical shape.

This effect is vividly demonstrated by the spherical shape of water droplets on a spider's web, like the one shown below.
