These are sand simulations with different cohesion values.

这些是关于不力值的沙地模拟。

They pull on each other and create a relatively strong cohesive force that traps you.

他互相拉扯并形成相当强的力把你困住。

That's what creates surface tension and it has a property called cohesion.

这就是产生表面张力的原因它有一种叫做力的特性。

Cohesion means the strength of intermolecular forces that hold the material together.

力指把物质结合在一起的子间作用力强度。

The higher cohesion is, the harder it is to break the sand up, the bigger the clumps are.

力越强，沙子也就越难被打散，沙子的块头就越大。

We wanted to give you something that reflects our love for you...

为了反映庭的力。

To the students, it seemed he had no cohesion.

在学生看来，他没有力。

These attractive, also called cohesive, forces pull the surface molecules inward.

这些吸引力，也称为力，将表面子向拉。

Now, the attraction or " cohesion" between the molecules in liquids give them some important properties.

现在，液体子之间的吸引力或“力”赋予了它一些重要的特性。

The water molecules stick to the cat’s tongue thanks to adhesive forces, and stick to each other because of cohesive forces.

由于粘附力，水子粘在猫的舌头上，并由于力相互粘在一起。

A third effect of cohesion can be observed by placing one end of a very narrow tube, called a " capillary tube" in a liquid.

通过将称为“毛细管”的非常窄的管的一端置于液体中，可以观察到力的第三种效果。

And what you see when you look at this pile of water is the result of those cohesive forces, minimized surface area in the water in this beaker.

当你看着这堆水时，你看到的是这些力的结果，这个烧杯中的水表面积最小。
