Why are the dewdrops mostly spherical, and the reason why the dewdrops are spherical

The surface tension causes the dew to exist in the state of minimal surface area.

Among the objects of equal volume, only the sphere has the smallest surface area, so the dew drops are mostly spherical.

However, due to the gravitational pull of the earth, the dew drops cannot be perfectly round!

It doesn't have much to do with the third day of September.

It's impossible to say it's okay.

Everything is connected.

The gravitational pull of the moon that day and so on.

Why is the dew rolling on the lotus leaf always spherical? Why are the falling raindrops always teardrop-shaped? This is due to the surface tension of the liquid.

Liquid surface tension is the result of intermolecular interactions. In the case of water, the water molecules inside are surrounded by other water molecules, and the gravitational pull of the molecules in all directions cancels each other out. However, the gravitational pull of the inner water molecules on the surface water molecules is much greater than that of the external air molecules.

Therefore, the water molecules on the surface are always subjected to the force directed towards the interior of the liquid and always tend to move inward. In this way, the liquid will always try to reduce its surface area. Whereas, for an object of the same volume, the surface area of the sphere is always the smallest.

The non-wetting of the water on the surface of the lotus leaf and the surface tension work together to make the water shrink into crystal dew drops on the lotus leaf. Raindrops appear teardrop-shaped under the combined action of surface tension and gravity.

The surface tension is not only in liquids, but also in solids, but because the solid molecules are arranged very closely, the molecules on the surface are not easy to "retract" into the interior of the solid, and this contraction force is not obvious.

If solids and liquids do not have surface tension, they will have no shape and volume like gases, and everything in the world will be ethereal.

There is both gravitational and repulsive force between molecules, and the dew looks spherical, in this case, it mainly shows the mutual attraction between water molecules and water molecules, that is, the effect of surface tension, because the surface tension always wants to reduce the surface area of the dewdrop, and the surface area of the ball is the smallest in the case of the same volume, so the dew is spherical

Therefore, b

Surface tension is also a tensile force.

Because the spherical surface area is minimal, and only the smallest surface area can maximize the amount between the water particles.

In order to produce the greatest stability, it is necessary to balance each other.

Therefore, under the influence of gravity, the dew is basically bead-shaped.

The smallest surface area can only be guaranteed by the formation of a sphere of matter of the same volume, which can be proved in solid geometry. In addition, under the action of gravity, the dew drops are slightly flattened on the plane, and they fall a little when hanging.
