Surface tension is also viewed as the result of forces acting in the plane of the surface and tending to minimize its area. On this basis, surface tension is often expressed as an amount of force exerted in the surface perpendicular to a line of unit length. The unit then is newtons per metre, which is equivalent to joules per square metre. Definition of surface tension : the attractive force exerted upon the surface molecules of a liquid by the molecules beneath that tends to draw the surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least surface area Examples of surface tension in a Sentence
Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties.
Surface tension. Viviane Rehberg. Thomas Ruff insists that his photographs capture only 'the surface of things'. But is there more than meets the eye? Surface tension is a force that acts to reduce the surface area of a liquid. · Molecules at the surface of a liquid experience a net attraction toward the interior of the ...
Surface tension is caused by the cohesive forces of liquid molecules at the water surface. The concept of surface tension can be visualized by the figure below. Figure 1: The effect of surface tension. As can be seen in the figure above, a certain head, h, is required to overcome surface tension and form a water droplet. Define surface tension. surface tension synonyms, surface tension pronunciation, surface tension translation, English dictionary definition of surface tension. n. 1.
Surface tension is caused by the inward attraction of molecules at a boundary. Surface tension is the energy required to stretch a unit change of surface area - and the surface tension will form a drop of liquid to a sphere since the sphere offers the smallest area for a definite volume.
