surface tension?

Answer 1

Yes I like the vonvex.

Answer 2

The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface. This forms a surface "film" which makes it more difficult to move an object through the surface than to move it when it is completely submersed.

Answer 3

In physics, surface tension is an effect within the surface layer of a liquid that causes the layer to behave as an elastic sheet. It is the effect that allows insects (such as the water strider) to walk on water, and causes capillary action, for example.

Surface tension is caused by the attraction between the molecules of the liquid, due to various intermolecular forces. In the bulk of the liquid each molecule is pulled equally in all directions by neighboring liquid molecules, resulting in a net force of zero. At the surface of the liquid, the molecules are pulled inwards by other molecules deeper inside the liquid, but there are no liquid molecules on the outside to balance these forces. (There may also be a small outward attraction caused by air molecules, but as air is much less dense than the liquid, this force is negligible.) All of the molecules at the surface are therefore subject to an inward force of molecular attraction which can be balanced only by the resistance of the liquid to compression. Thus the liquid squeezes itself together until it has the lowest surface area possible.

Surface tension, measured in newtons per meter (N·m-1), is represented by the symbol σ or γ or T and is defined as the force along a line of unit length perpendicular to the surface, or work done per unit area.

Dimensional analysis and the work-energy theorem show that the units of surface tension (N·m-1) are equivalent to joules per square metre (J·m-2). This means that surface tension can also be considered as surface energy. If a surface with surface tension σ is expanded by a unit area, then the increase in the surface's stored energy is also equal to σ.

A related quantity is the energy of cohesion, which is the energy released when two bodies of the same liquid become joined by a boundary of unit area. Since this process involves the removal of a unit area of surface from each of the two bodies of liquid, the energy of cohesion is equal to twice the surface energy. A similar concept, the energy of adhesion, applies to two bodies of different liquids. Energy of adhesion is linked to the surface tension of an interface between two liquids. W_{adh}=W_{coh}^{\alpha}+W_{coh}^\beta-\gamma_{\alpha}^\beta

Answer 4

what you feel when you hit the surface of something, depending on the velocity of the impact your tension will be greater. I know this is not what you are looking for but you aren't being very clear so, not a clear answer you shall receive.

Answer 5

uhm, way to have a fragment and try to pull it off as a question...if you are asking what surface tension is however, it is caused by the attraction of atoms and molecules to one another. more specifically, the surface tension in water is caused by cohesion and adhesion.

Answer 6

this is the tension exerted by a body on the surface .

Answer 7

whats the question?
what surface tension? are you asking the defination?
please frame your questions properly.

Answer 8

its the force acting on liquid in a direction normal to its surface/unit area

Answer 9

no tension cool

Answer 10

u were expecting maybe...lorenz factor?

PS Karans's answer is correct
