In this article, you will learn to derive the dimensional formula of surface tension using the formula, Surface Tension = Force / length. Surface tension is a fundamental concept in physics that describes the cohesive forces acting at the surface of a liquid. It is responsible for the behaviour of liquids, such as droplets forming spherical shapes and objects floating on water despite being denser. This force arises due to the intermolecular attractions between molecules at the liquid's surface. Here, we will explore the concept of surface tension, its definition along with the SI unit, formulas and examples. Surface tension is the tendency of fluid surfaces to shrink into the minimum surface area possible. Have you noticed when you fill a glass up to the brim with water, you can still add a few more drops till it spills out? Or have you ever broken a thermometer and observed how the fallen mercury behaves? All these happen due to the surface tension of the surface. Let us understand the concept, surface tension definition along with its SI unit, formula and examples. Explore the dimensional formula of surface tension along with its detailed derivation. Learn about the dimensions of other physical quantities like momentum, stress, rotational kinetic energy, Boltzmann constant, and impedance.
