About the properties of waterWhat is the difference between cohesive force and high surface tension p.s.Chinese is available.
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.This forms a surface "film" which makes it more difficult to move an object through the surface than to move it when it is completely submersed.
The cohesive forces between molecules down into a liquid are shared with all neighboring atoms.Those on the surface have no neighboring atoms above,and exhibit stronger attractive forces upon their nearest neighbors on the surface.This enhancement of the intermolecular attractive forces at the surface is called surface tension.

I think that maybe you English is very well

Cohesive force is the force of attraction between the molecules of the same substance when they are close enough.
Surface tension is due to the cohesive force, but determined by all of the substances forming the interface,which we call it adhesion.
for example, cohensive force is invariable in water, while the surface tension of water in air is different with that in oil.

内聚力(cohesive force )又叫粘聚力,是在同种物质内部相邻各部分之间的相互吸引力,这种相互吸引力是同种物质分子之间存在分子力的表现。只有在各分子十分接近时(小于10-6厘米)才显示出来。内聚力能使物质聚集成液体或固体。特别是在与固体接触的液体附着层中,由于内聚力与附着力相对大小的不同,致使液体浸润固体或不浸润固体。

表面张力(surface tension)的定义
①促使液体表面收缩的力叫做表面张力[1]。
②液体表面相邻两部分之间,单位长度内互相牵引的力。
区别:内聚力(cohesive force )是指不同物质分子间的吸引,比如让水浸入木头。但是张力(surface tension)是指同一物质液体表面的分子互相吸引在一起。比如矿泉水上面可以漂浮一根针。
