For example,we can see a little drop of water is on intimate terms with ball on the grass after rain.The mercury is close to ball on the ground when we break thermograph and let the silver out.On the other hand,we can perform a magic with a glass of water,putting a needle on the surface carefully .Then we can see the needle flutter without sinking,at the sane time forming hollow side under the needle
Then what's the surface tension?When liquid get in touch with gas,it form a surface layer. The mutual attraction inside this layer is surface tension.It can lead to shrink of surface of liquid automatically.The formation of surface tension due to the great cohesive force of molecularities of liquid.The 网出品 number of molecularities in surface is less than one inside.So they are given the force directing inside making the surface like a rubber film.They are inclined to shrink so as to reduce the surface a As we know,the spherical subject has thallest area in the same volume.Therefore,because of surface tension,the small drop of liquid attempt to keep spheroid.This is the 气相 reason why the drop of water approach to spheroid.The direction of surface tension is contact 不 with liquid surface.And it is vertical with any line of demarcation belonging to two parts of liquid At last the surface tension is only relevant to temperature
Then ,what’s the surface tension? When liquid get in touch with gas,it form a surface layer. The mutual attraction inside this layer is surface tension.It can lead to shrink of surface of liquid automatically. The formation of surface tension due to the great cohesive force of molecularities of liquid. The number of molecularities in surface is less than one inside. So they are given the force directing inside making the surface like a rubber film. They are inclined to shrink so as to reduce the surface area. As we know,the spherical subject has the smallest area in the same volume. Therefore,because of surface tension,the small drop of liquid attempt to keep spheroid. This is the reason why the drop of water approach to spheroid. The direction of surface tension is contact with liquid surface. And it is vertical with any line of demarcation belonging to two parts of liquid. At last,the surface tension is only relevant to temperature

Chinese scientists have proved Chinese scientists have proved something called Chow water insects is something called Chow water insects is how to achieve a stable standing on the how to achieve a stable standing on the surface and not the sunken mystery surface and not the sunken mystery Water Chow has been able to live in security on the Water Chow has been able to live in security on the water surface, standing or water surface, standing or walking fast, as some walking fast, as some researchers have to think, rely on the secretion of oil researchers have to think, rely on the secretion of oil produced to the surface tension effects. In fact, the produced to the surface tension effects. In fact, the increase in water use their legs to a special increase in water use their legs to a special classification to micro classification to micro -nano -structure to achieve the structure to achieve the effect of super effect of super-hydrophobic properties. hydrophobic properties
