تعريف surface tension في الإنجليزية الإنجليزية القاموس.

a measure of this effect

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

Particles lying below this film, being equally acted on from all sides, are in equilibrium as to forces of cohesion, but those in the film are on the whole attracted inward, and tension results

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

a phenomenon at the surface of a liquid caused by intermolecular forces

An inward tension acting to make a surface as small as possible It appears when a surface has extra potential energy

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 has properties resembling those of a stretched elastic membrane

The energy required to expand the surface of liquid by unit area Liquids tend to reduce their surface area due to unequal intermolecular attractive forces in this region A low degree of surface tension is preferred for liquid coatings to maximize adhesion and minimize edge-pull and fish-eye effects

Energy per unit area

is the force per unit length used to overcome the microscopic forces between molecules at the liquid-air interfaces is the force per unit length used to overcome the microscopic forces between molecules at the liquid-air interfaces

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 force that controls the shape of a liquid Surface tension results from the force of a cohesion between liquid molecules

The thickness of this film, amounting to less than a thousandth of a millimeter, is considered to equal the radius of the sphere of molecular action, that is, the greatest distance at which there is cohesion between two particles

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

the property, due to molecular forces, by which all liquids through contraction of the surface tend to bring the contained volume into a form having the least area If an ink is to be compatible with a substrate, the surface tension of the ink must approximate that of the substrate surface Measured in dynes/cm

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

the tension of the surface film of the liquid, tending to minimize its surface area

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 property (measured in dynes per centimeter) by which all liquids through contraction of the surface tend to bring the contained volume into a form having the least area If an ink is to be compatible with a sustrate, the surface tension of the ink must be close to that of the substrate

(noun) The contracting force on the skin of a liquid Acts like a rubber balloon on a liquid droplet, for example, and will exert a force to form a three dimensional shape of the smallest surface energy, e g , a sphere

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

– the ratio of the surface force to the length along which it acts

That property, due to molecular forces, which exists in the surface film of all liquids and tends to bring the contained volume into a form having the least superficial area

The attraction of a liquid for any material with which it has contact A high surface tension means low attraction and a low surface tension means a high degree of attraction Water has a high surface tension so it beads on wax paper If you add soap to the water it reduces the surface tension and causes the water to penetrate the wax paper

The property (measured in dynes per centimeter) by which all liquids, through contraction of their surface, forcing the contained volume into a form having the least possible area In order to be compatible, ink must have a surface tension close to that of the substrate

Tension of a liquid's surface Due to the forces of attraction between molecules

The contracting force per unit length around the perimeter of a surface is usually referred to as surface tension if the surface separates gas from liquid or solid phases, and interfacial tension if the surface separates two nongaseous phases Surface tension can also be expressed in units of energy per unit surface area For practical purposes surface tension is frequently taken to reflect the change in surface free energy per unit increase in surface area

the way the molecules in the surface of a liquid stick together so that the surface is held together. Property of a liquid surface that causes it to act like a stretched elastic membrane (see elasticity). Its strength depends on the forces of attraction among the particles of the liquid itself and with the particles of the gas, solid, or liquid with which it comes in contact. Surface tension allows certain insects to stand on the surface of water and can support a razor blade placed horizontally on the liquid's surface, even though the blade may be denser than the liquid and unable to float. Surface tension results in spherical drops of liquid, as the liquid tends to minimize its surface area

the resistance of a liquid to an increase in its surface area

Property of liquidus created by molecular forces existing in the surface film It tends to contract the volume into a form with the least surface area Breakdown of surface tension can be accomplished by addition of certain chemical agents, resulting in the liquid flowing out and wetting surrounding material surfaces One of the functions of flux in the soldering process is to breakdown surface tension of solder, thereby causing solder to wet metal surfaces to be jointed Surface tension is higher in nitrogen than in air
