Surface tension, английский
- Tension superficielle
- The contractile surface force of a liquid by which it tends to assume a spherical form and to present the least possible surface. it is expressed in dynes/cm or ergs/cm2.
- The force per unit length acting in the surface of a liquid that opposes the increase in area of the liquid (spreading).
- Intermolecular forces acting on the molecules at the free surface of a liquid tend to minimize the surface area of the liquid and give the surface properties similar to those of an elastic skin under tension. when two dissimilar liquids make contact, these intermolecular forces will cause the shape of the interface to change until the potential energy of the entire molecular system is at a minimum.
- The cohesive force at the surface of a liquid that causes the surface to contract and assume a spherical form resembling a stretched elastic membrane.
- The attractive force exerted by molecules below the surface upon molecules at the surface/air interface. the strength of the surface tension varies with the polarity of the liquid; high-polar substances like water have higher surface tension than low-polar substances like organic solvents and oils.
- Characteristic of liquids where the outer surface contracts to the smallest possible area. t
- Characteristic of liquids where the outer surface contracts to the smallest possible area.
