Surface tension is a property of the surface of a liquid. It is what causes the surface portion of liquid to be attracted to another surface, such as that of another portion of liquid (as in connecting bits of water or as in a drop of Mercury that forms a cohesive ball).
Surface tension is caused by cohesion (the attraction of molecules to like molecules). Since the molecules on the surface of the liquid are not surrounded by like molecules on all sides, they are more attracted to their neighbors on the surface.
Applying Newtonian physics to the forces that arise due to surface tension accurately predicts many liquid behaviors that are so commonplace that most people take them for granted. Applying thermodynamics to those same forces further predicts other more subtle liquid behaviors.
Surface tension has the dimension of force per unit length, or of energy per unit area. The two are equivalent-but when referring to energy per unit of area, people use the term surface energy-which is a more general term in the sense that it applies also to solids and not just liquids.
In materials science, surface tension is used for either surface stress or surface free energy.
The molecules constituting a liquid exert attractive forces on each other. A molecule in the interior of the liquid is surrounded by an equal number of neighboring molecules in all directions. Therefore, the net resultant intermolecular force on an interior molecule is zero.
What else can I help you with?
What is an example of an organism that benefits from reducing surface tension?
Humans benefit greatly from the work of Pulmonary surfactant which reduces the surface tension in the alveoli of the lungs. This reduction in alveolar surface tension prevents the alveoli from collapsing and thus causing suffocation.
What is surface tension coefficient?
Surface tension coefficient, also known as surface tension, is the force acting on the surface of a liquid that causes it to behave like a stretched elastic membrane. It is a measure of the strength of the attractive forces between molecules at the surface of a liquid. The higher the surface tension, the more difficult it is to break the surface of the liquid.
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.
What surface of water can act like a sort of skin due to a property of liquids called?
Surface tension.

What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
How do you break the surface tension?
Adding surfactants the surface tension decrease.
Does water have the highest surface tension?
No, mercury has a higher surface tension.

What is a force that acts on particles at a liquids surface?
Surface tension is the force that acts on particles at a liquid's surface. It is caused by the cohesive forces between the liquid molecules, which creates a barrier that resists the penetration of external objects or forces. This force is responsible for phenomena such as capillary action and the formation of droplets.
Effect of Temperature on Surface Tension?
surface tension decreases with the increase of temperature
How does temperature affect surface tension?
As the temperature rises, surface tension decreases.
Is surface tension a solid liquid or gas?
Surface tension is a characteristic of liquids.
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
How does surface tension work and what are its effects on liquid behavior?
Surface tension is a property of liquids that causes the molecules at the surface to stick together, forming a "skin" on the surface. This creates a barrier that resists external forces, such as gravity or objects placed on the surface. Surface tension affects the behavior of liquids by allowing them to form droplets, support objects on their surface, and exhibit capillary action, where liquids can move against gravity in narrow spaces.
What is the scientific name for surface tension?
The scientific name for surface tension is interfacial tension. It refers to the property of a liquid that causes its surface to act like a thin, elastic sheet.
