What is surfantant?
Also called surface-active agent, it is a substance such as a detergent, that can reduce the surface tension of a liquid and thus allow it to foam or penetrate solids; a wetting agent
How does surface tension affect your environment?
Surface tension affects everyone's environment in many ways. Surface tension is the property of water that makes life to exist as we are accustomed. Surface tension also makes our body cells functional.
What is wetting in dentistry?
It has to do with adhesion in dentistry. Wetting depends on the surface property and surface tension. Wetting also is a qualitative description of contact angle. When you have a high surface tension you have low wetability, a large contact angle and low surface energy. And the opposite for a low surface tension. When two objects are very different in their energies you have less wetting such as water and wax. If metal is the solid (metal has a high surface energy) then wetting is increased.
What do cohesive surface tension and adhesion have in common with reference to water?
Cohesion: When things stick to each other (WATER) Adhesion: When things stick to other things (ALSO WATER) Surface Tension: a property of the surface of a liquid that causes it to behave as an elastic sheet. Think of it as the thing that helps insects to glide along the water. (ALSO WATER)
Liquids form spherical drops because of what property?
Liquids tend to form spherical droplets because of surface tension. There is energy associated with the surface tension, and since a sphere has the minimum surface to volume ratio, it has the minimum surface tension related energy for a given amount of liquid. (It is a general principle in physics that things tend toward a minimum energy state.)
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.
Why can you pour a glass of water to the rim of the glass?
it's called "surface tension". It is the property of the surface of a liquid which causes it to behave like an elastic sheet. This is why a "water strider" insect can skate across the surface of a pond without sinking into the water. It is also what causes a drop of water - the surface tension of the water pulls it into a ball.
What are the Biological importance of high surface tension?
High surface tension in water allows certain organisms, like insects, to walk on water. This property also helps plants draw water from roots to leaves through capillary action. Additionally, high surface tension enables water to form droplets, which aids in the transportation of nutrients and waste in living organisms.
What is the relationship between density and surface tension?
as we know the relation between surface tension and temperature is inverse, and that of temperature and density also has inverse proportion, then it is clear that the '''surface tension is directly proportion to the density'''.
What liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.

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.

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.
