Surface Tension :: essays research papers fc

Surface TensionMy problem was to key out how to test or measure near tensity. I hark back the reason of some of the take in in rear tension is viscidity andgravity. Surface Tension is the condition existing at the free surface of a fluid, resembling the properties of an elastic skin under tension. The tensionis the result of intermolecular sticks exerting an unbalanced inward pull onthe individual surface molecules this is reflected in the considerablecurvature at those edges where the liquid is in contact with the jetty of avessel. Because of this property, certain insects can stand on the surface ofwater. A razor blade can besides be supported by the surface tension of water. Therazor blade is not floating if pushed finished the surface, it sinks throughthe water. More specifically, the tension is the force per unit length of bothstraight line on the liquid surface that the surface layers on the oppositesides of the line exert upon each other. The tendency of any liquid surface isto become as small as possible as a result of this tension, as in the case ofmercury, which forms an almost refresh ball when a small quantity is placed on ahorizontal surface. The near-perfect spherical shape of a soap bubble, which isthe result of the scattering of tension on the thin film of soap, is anotherexample of this force surface tension alone can support a chevy placedhorizontally on a water surface.Surface tension depends mainly upon the forces attraction between theparticles within the given liquid and also upon the gas, solid, or liquid incontact with it. The molecules in a frame of water, for example, attract eachother weakly. Water molecules well inside the frame may be thought of as beingattracted equally in all directions by the surrounding molecules. However ifsurface molecules could be displaced approximately outward from the surface, theywould be attracted back by the near by molecules. The readiness responsible forthe phenomenon of surface ten sion may be thought of as approximately equilivantto the work or energy required to remove the surface layer of molecules in aunit area. In comparison, organic liquids, much(prenominal) as benzene and alcohols, havelower surface tensions, whereas mercury has a higher surface tension . Anincrease in temperature lowers the net force of attraction among molecules andhence decreases surface tension.Surface tension is also viewed as the result of forces acting in theplane of the surface and tending to lessen its area. On this basis.
