At liquid–air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion). [1] There are two primary mechanisms in play. One is an inward force on the surface molecules causing the liquid to contract.
Oct 6, 2023 · Surface tension is the force per unit length or energy per unit area of a liquid surface. Learn how it is caused by intermolecular forces, how it affects cohesion and adhesion, and what are its values for different liquids.
Learn what surface tension is, how to measure it and how it varies with temperature and fluid type. Find tables of surface tension values for common fluids in different units, such as N/m, dyn/cm, J/m2 and erg/cm2.
Dec 20, 2022 · Learn about the physical property of surface tension, which is the amount of force required per unit area to expand the surface of a liquid. Find out the formula, unit, causes, examples, and consequences of surface tension, as well as how to measure it.
Sep 24, 2024 · surface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. Because of this property, certain insects can stand on the surface of water.
Jan 30, 2023 · Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties.
