What is serface tention?

Surface tension is a physical property of liquids that arises from the cohesive forces between molecules at the liquid's surface. It causes the surface to behave like a stretched elastic membrane, allowing it to resist external force and minimize surface area. This phenomenon is responsible for various effects, such as the ability of small objects to float on water and the formation of droplets. Surface tension is influenced by factors like temperature and the presence of surfactants.
