Surface Tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area. 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. ... The razor blade is not floating: if pushed through the surface, it sinks through the water. Tension Formula. The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. T = mg + ma. Add a couple drops of soapy water to the surface of the water using a dropper. Do this where the paperclip is floating. But be careful to add it to the water away from the paperclip. The soapy water should break the surface tension of the water, causing the paperclip to fall to the bottom of the container. Y= 1/2 x F/L
The dimensional formula of surface tension is: [ML0T-2].
Liquid: Surface Tension (N/m)
Water: 72.7
Hydrogen: 2.4
Helium: 0.16. Surface and interfacial tensions are phenomena that affect our everyday life. ... High surface tension of water is also the reason why rain comes down as a spherical drop. High surface energy drives the water drop to take a shape with as little surface area as possible, making a sphere shape most favorable. Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken.
