Topic: surface tension, coefficient of surface tension

Surface Tension The surface of a liquid behaves in such a way that it is cover with an elastic skin. This elastic skin allow some tiny objects with a density higher than the density of water (for example) to float on its surface. If a tiny needle is drop on a surface of water  the needle floats despite the density of the needle higher than the density  of the water. Surface tension can be defined as the force acting parallel on the surface of a liquid which does not allow tiny objects of h...
