Surface tension definition, the elasticlike force existing in the surface of a body, especially a liquid, tending to minimize the area of the surface, caused by asymmetries in the intermolecular forces between surface molecules. When we walked into the room after their argument, we could feel the tension in the air. 227 sentence examples: 1. From this the weight of a drop of any liquid of which the density and surface tension are known, can be calculated. Steam actuation is also a serious possibility for micro-engineered devices, although surface tension effects caused by liquid water must be taken into account. Better driv-ing equipment will improve track adhesion in slippery conditions. The results show the surface-active agent used by the experiments can reduce the capillary pressure and the, 27. 2. Click on … In all these cases the internal pressure exceeds the external by 2T/a where a is the semi-transverse axis of the conic. Introduced transition of a new type of welding technique -, 30. tensiometer used to measure dynamic surface tension of fluids. It is possible that a correlation may be made between solubility and the energy of surface tension.

It assumes the form of a sphere under the action of surface-tension alone. If gravity and surface tension did not predominate, the water drops on the surface would still be spherical as well. Login . If the surface is between two liquids (such as water and oil), it is called "interface tension." Surface tension is defined as the elasticlike force that exists at the surface. From the Cambridge English Corpus The origin of the forces driving convection depends upon the depth of the fluid, with surface tension forces dominating in sufficiently thin layers.

If a drop of water be allowed to form at the extremity of a fine tube, it will go on increasing until its weight overcomes the surface tension by which it clings to the tube, and then it will fall. It doesn't look like it. Most students feel tense before the speaking test. Phenomena arising from the Variation of the Surface-tension.- Pure water has a higher surface-tension than that of any other substance liquid at ordinary temperatures except mercury. What is Surface Tension? Examples of how to use “surface water” in a sentence from the Cambridge Dictionary Labs These motor units are supported on the surface of the water by an intensifying of the surface tension in their immediate area. The resultant of the internal pressure and the surface-tension is equivalent to a pressure along the axis equal to that due to a pressure p acting on a circle whose diameter is the conjugate axis of the hyperbola. The form into which he threw his investigation seems to have deterred many able physicists from the inquiry into the ulterior cause of capillary phenomena, and induced them to rest content with deriving them from the fact of surface-tension. The forces acting on the portion of liquid P 1 P 2 A 2 A 1 are - first, the horizontal pressures, - pgy i and z pgy 2; second, the surface-tension T acting at P i and P2 in directions inclined 01 and 0 2 to the horizon. we may define T either as the surface-energy per unit of area, or as the surface-tension per unit of contour, for the numerical values of these two quantities are equal. It was true Lily was extraordinarily prim … 1. However, as bubbles expand the internal pressure overcomes the surface tension and the bubbles grow rapidly. But this equation is applicable only at points in the interior, where p is not varying.] The intensity of this surface-tension is measured by the stress which it exerts across a line of unit length. The model uses simulated surface tension and an inflationary force to grow from within an object and find its boundary. 28. In the next place, there is the surface-tension acting downwards, but at an angle a with the vertical, across the circular section of the bubble itself, whose circumference is 21ry, and the downward force is therefore 2lryT cos a. Hence any impurity which diminishes the surface tension of the water will diminish the size of the drop (unless the density is proportionately diminished). Sample answer: A liquid with a high viscosity does not flow very easily. And when you wash your hands, when we use detergents. The surface tension, on the other hand, is greater than that of pure water and increases with the salinity, according to Kriimmel, in the manner shown by the equation a=77.09+o 0221 S at o° C., where a is the coefficient of surface tension and S the salinity in parts per thousand. p. 620) experimented on liquid films, and showed how a film of a liquid of high surfacetension is replaced by a film of lower surface-tension.

Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight. Surface tension is a property of liquids where the exposed surface shrinks to the smallest possible area because of unequal forces near the surface. This drop will not spread out like the first drop, but will take the form of a flat lens with a distinct circular edge, showing that the surface-tension of what is still apparently pure water is now less than the sum of the tensions of the surfaces separating oil from air and water. According to Quincke, the surface tension of pure water in contact with air at 20° C. is 81 dynes per linear centimetre, while that of alcohol is only 25.5 dynes; and a small percentage of alcohol produces much more than a proportional decrease in the surface tension when added to pure water. Similar words: adhesive, cohesion, hesitation, adhere, lesion, adhere to, adherent, adherence. Examples of Adhesion in a sentence. The surface tension, on the other hand, is greater than that of pure water and increases with the salinity, according to Kriimmel, in the manner shown by the equation a=77.09+o 0221 S at o° C., where a is the coefficient of surface tension and S the salinity in parts per thousand.

Free-moving liquid in outer space will form itself into a sphere because of its surface tension. An application of the finger for 20 or 30 seconds to the under surface of the vessel will then generate enough heat to lower appreciably the surface-tension, as is evidenced by the opening out of the dust and the formation of a bare spot perhaps r z in. As the separating oceanic crust cools over time, it becomes more dense and sinks farther and farther away from the ridge axis. The wall paper is starting to peel because its adhesion has decreased in strength over the years. What does surfactant mean? It is there shown that the surface tension of a liquid may be calculated from its rise in a capillary tube by the formula y = rhs, where y is the surface tension per square centimetre, r the radius of the tube, h the height of the liquid column, and s the difference between the densities of the liquid and its vapour. For example, water striders use surface tension to walk on the surface of a pond.

Another word for tension. of the phenomena of surface-tension, and showed their connexion with the experiments of Charles Tomlinson on the figures formed by oils dropped on the clean surface of water. The polyvinylidene fluoride ( PVDF ) resin shows very low critical. For example, if a drop of alcohol be placed on the surface of water, the surface-tension will be diminished from 80, the value for pure water, to 25, the value for pure alcohol. 0. (6) or the force arising from the surface-tension acting on a length a of the strip is Ta, so that T represents the surface-tension acting transversely on every unit of length of the periphery of the liquid surface. A certain amount of mechanical energy is thus used to create the droplets, and is consequently stored as surface tension energy. Tables Of Surface-Tension In the following tables the units of length, mass and time are the centimetre, the gramme and the second, and the unit of force is that which if it acted on one gramme for one second would communicate to it a velocity of one centimetre per second: - Table of Surface-Tension at 20° C.

He adds that the line between accession and adhesion is poorly defined. If, however, the energy of surface tension between the two substances were negative the surface would tend to a maximum, and complete mixture would follow. 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. According to the definition of surface tension, it is the phenomenon that occurs when the surface of a liquid is in contact with another phase (it can be a liquid as well). 2. tendency of molecules of a liquid to be attracted more towards one another at the surface of a liquid than to the air 29.
