Question

Смачивает ли ртуть стекло? почему?

Answer 1

Не смачивает, потому что сила притяжения между атомами ртути больше, чем сила притяжения атомов ртути к атомам, входящим в состав стекла.
Но проще сказать стекло твёрдое, а ртуть плотная, поэтому нет

Answer 2

Can Mercury Wet Glass?

Yes, mercury can wet glass. This is due to the cohesive and adhesive properties of mercury. When a small amount of mercury is placed on a clean glass surface, it forms a nearly spherical shape due to its cohesive forces. The adhesive forces between mercury and glass are stronger than the cohesive forces within the mercury, causing it to spread out and wet the glass surface.

The cohesive and adhesive properties of mercury play a significant role in its behavior on different surfaces, including glass. The interaction between the molecules of mercury and the molecules of the glass surface leads to the wetting phenomenon observed when mercury is in contact with glass.

In summary, mercury can wet glass due to the cohesive and adhesive forces between the mercury and the glass surface
