Question

Почему капля ртути имеет форму шара? я думаю С любых неровностей атомы ртути испаряются быстрее поэтому все выступы на капле быстро исчезают. ЭТО ВЕРНО?

Answer 1

жидкости стремяться занять как можно меньший объем , а это шар

Answer 2

Why does a mercury droplet have a spherical shape?

A mercury droplet has a spherical shape due to the intermolecular forces acting on its surface. These forces, known as surface tension, cause the liquid to minimize its surface area and form a shape with the least surface area, which is a sphere. The cohesive forces between the mercury atoms pull the liquid inward, creating a spherical shape.

The spherical shape of a mercury droplet can be explained by the balance between the cohesive forces within the liquid and the adhesive forces between the liquid and its surroundings. The cohesive forces tend to pull the liquid molecules together, while the adhesive forces between the liquid and its container or other surfaces tend to spread the liquid out. In the case of mercury, the cohesive forces are stronger than the adhesive forces, resulting in a spherical shape.

It is important to note that the shape of a mercury droplet can also be influenced by other factors, such as gravity and external forces. However, the inherent surface tension of the liquid tends to maintain a spherical shape.

In summary, the spherical shape of a mercury droplet is primarily due to the intermolecular forces of surface tension, which cause the liquid to minimize its surface area and form a shape with the least surface area, which is a sphere.
