surface tension

noun, Physics.
1.
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.

surface tension

noun
1.
a property of liquids caused by intermolecular forces near the surface leading to the apparent presence of a surface film and to capillarity, etc
2.
a measure of this property expressed as the force acting normal to one side of a line of unit length on the surface: measured in newtons per metre T, γ, σ

surface tension in Medicine

surface tension n.

  1. A property of liquids arising from unbalanced molecular cohesive forces at or near the surface, as a result of which the surface tends to contract and exhibit properties resembling those of a stretched elastic membrane.

  2. A measure of this property.

surface tension in Science
surface tension
  (sûr'fəs)   
A property of liquids such that their surfaces behave like a thin, elastic film. Surface tension is an effect of intermolecular attraction, in which molecules at or near the surface undergo a net attraction to the rest of the fluid, while molecules not near the surface are attracted to other molecules equally in all directions and undergo no net attraction. Because of surface tension, the surface of a liquid can support light objects (such as water beetles on the surface of a pond). Surface tension is responsible for the spherical shape of drops of liquid; spheres minimize the surface area of the drop and thus minimize surface tension. See also capillary action, meniscus.

surface tension definition


The force exerted along the surface of a fluid that causes it to “bead up” and form into drops. Water has high surface tension and beads up easily; alcohol has low surface tension and does not often show droplets.
