A measure of how difficult it is to stretch or break the surface of a liquid. Water has a high surface tension because of the hydrogen bonding of surface molecules.

Surface free energy that exists between a liquid and air. Surface tension can be observed as a curved meniscus in a small tube of the liquid. This energy barrier prevents a liquid (such as water) from [..]

The elastic-like force at the surface of a liquid, tending to minimize the surface area and causing drops to form. Expressed as Newtons per meter or dynes per centimeter (1 Newton/m=1,000 dynes/cm). 

The work required to expand the surface of a liquid by unit area.

property of the surface of a liquid where the molecules act like a thin, elastic film, allowing it to resist external forces.

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.

Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. Surface tension forces are due to intermolecular forces between the liqui [..]

the mutual attraction of water molecules at the surface of a water mass that creates a flexible molecular "skin" over the water surface surface-to-volume ratio (S/V ratio)

The inherent molecular attraction in liquids that causes them to diminish their surface area and thereby exhibit properties resembling those of a stretched elastic membrane.

the attraction of molecules to each other on a liquid's surface. Thus, a barrier is created between the air and the liquid.

A property of liquids in which the exposed surface tends to contract to the smallest possible area, as in the formation of a meniscus. It is caused by unequal molecular cohesive forces near the surfac [..]

The attractive forces which liquid molecules have for each other. Surfactant

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 elastic-like force in a body, especially a liquid, tending to minimize, or constrict, the area of the surface.

The tendency of a liquid surface to contract; the measure of this tendency in newtons per meter.

(physics) the effect on the surface of a liquid that makes it behave as a stretched elastic membrane; it is caused by unbalanced intermolecular forces (physics) a measure of this effect

Forces are acting between molecules which are resposible for the coherence of solids and liquids. The physical factor representing this interaction is the surface tension with the unit Newtons per square meter [N/m²] respectively [mN/m²]. The tendency of liquid drops to maintain a spherical shape is the result of the surface tension because the sph [..]

the property, due to molecular forces in the surface film, that tends to contract the liquid into a form having the least surface/volume ratio.

The force acting on the surface of a liquid, tending to minimize the area of that surface.  (see RFF 705.10.03 - SURFACE TENSION).

the force that causes the surface of a liquid to contract, reducing its surface area to a minimum.

The force acting on the surface of a liquid, tending to minimize the area of the surface. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)

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 dyne/cm or ergs/cm.

Tension exhibited by the free surface of liquids measured in dynes per centimeter.

The attractive force exerted upon the surface molecules of a liquid by the molecules beneath the surface. When oil is spilled on water, this tension makes the oil behave as a continuous sheet that is [..]

The attraction of molecules to each other on a liquid's surface. Thus, a barrier is created between the air and the liquid.

the elastic-like force in a body, especially a liquid, tending to minimize, or constrict, the area of the surface.

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.

An attrative property between molecules on the surface of a liquid and those beneath that cause a liquid to pool into the smallest possible surface area, resembling a stretched elastic membrane.

(physics) the effect on the surface of a liquid that makes it behave as a stretched elastic membrane; it is caused by unbalanced intermolecular forces (physics) a measure of this effect
