What do cohesion and surface tension have in common with reference to water?
Between water molecules a big cohesion force exist; this is the cause of the high surface tension of water.
What is the difference between viscosity and surface tension?
Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules. Of course, viscosity is resistance of flow and surface tension of lateral force but viscosity is s display of frictional force during laminar flow caused due to intermolecular forces. The surface tension is a function of cohesive forces generated by intermolecular forces among similar molecules. Very rightly since both the parameters are dynamic in natures and hence a 3rd parameter noted as friccohesity is most advanced version of the contribution of the intermolecular forces operational in liquid dynamic behavior. The friccohesity along with surface tension, viscosity, wetting coefficient, interfacial tension are measured with borosil mansingh survismeter.
What makes water have surface tension?
Surface tension is The attraction of molecules to each other on a liquid's surface? Surface tension of water is the physical property of hydrogen bonding that makes the water molecule. The way that this works is that a water molecule (H2O) is a polar molecule. This is because the oxygen has a much higher electronegative value than the hydrogen. This means that the oxygen gets a lot higher 'share' of the shared electrons than the hydrogen does. This gives oxygen a very high partialnegative charge, and the hydrogen a very high partial positive charge. Because of these high partial charges on each end of the molecule, they are very highly attracted to each other
What casues surface tension?
water
How concentration affect surface tension?
As the strength of intermolecular forces(IMFs) increases, vapor pressure decreases. This is because when IMFs are stronger it is harder for the compound to go to the gas phase, this means that the pressure the compound is exerting on the surrounding environment is lower.

What is surface tension.?
Surface tension is defined as the elasticlike force that exists at the surface.
What is the water tension?
Cohesive forces between liquid molecules on the surface cause a phenomenon known as surface tension. Due to the lack of surrounding molecules, surface molecules adhere more strongly to another than they would inside a liquid. Surface tension is measured in newtons per meter (N/m) or dyne per centimeter (dyn/cm). The formula to figure surface tension is gamma equals the ratio of the surface force to the distance along which the force acts or gamma = F / d. Variables such as temperature and solution purity can cause F to vary. Pure water at 20 degrees (C) has a surface tension of 72.8 dynes/cm.

The friction between the ground and molecules in the air cause the wind to be what?
it will be slower near the surface

What caused surface tension in water?
Simple Answer:Surface tension is a consequence of the cohesive forces that keep the molecules all together. The molecules in water are attracted to each other by electrostatic forces. The essential point is that the water molecules on the surface are not attracted to the air molecule as much as to the other water molecule at the side and below it; this causes the water body want to reduce the surface area as much as possible. When something pushes to the surface slightly, this cause the surface area bigger and the cohesion forces try to minimize that, causing the tension we can observe.Same Answer Said Differently:Water has a somewhat higher surface tension than many other liquids becausethe disruption of the forces between molecules at the surface weakens the molecular attraction significantly and the molecular forces were rather large to begin with, so the energy lost in forming the surface is large.Surface tension is the force that resists deformation of a surface of a liquid. (Solids have this too, but that is more complex.) The cohesive forces in a liquid minimize the energy of the liquid by minimizing the surface area. It take force to overcome this cohesion and that results in surface tension.Water molecules are special in that they have strong dipolar forces and the force of attraction therefore depends substantially on the orientation of the molecule relative to one another. The surface restricts the number and orientation of neighboring molecules, costing energy and creating significant surface tension.See related links and related questions for more.Surface tension in water is caused by molecules pulling equally in every direction to create a net force of zero and preventing items to submerge.
What is the leading cause of surface tension in most common liquids?
I believe all liquids have intermolecular forces of attraction between the molecules, whether they are small forces such as dispersion forces or stronger ones like hydrogen bonding in water etc. When in, "Bulk" such as in the middle of a liquid (not the surface) these forces are experienced all around the molecule in equal amounts and therefore no net force is experienced. However, at the surface of the liquid there are no attraction forces from above and so the molecules experience a net downwards pull. This causes the molecules at the surface to be pulled into the liquid, compressing the space at the surface. This smaller, denser and more packed surface is what causes the surface tension...correct me if I'm wrong. :)
What is water's surface tension?
Here are some explanations of surface tension:Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water too. It allows small objects, even metal ones such as needles, razor blades, or foil fragments, to float on the surface of water, and it is the cause of capillary action.5.18 pounds / feet at 0 degree Celsius. Or as I remember it is 72 dyne / centimeter at 25 degree Celsius. The surface tension of water is the force required in order to float at the water's surface, hence making water to behave like an elastic sheet.Water surface tension is contractive tendency of the surface of a liquid that allows it to resist an external force. The beading of water on a waxy surface, such as a leaf, is an example of water surface tension.
