Answer 2

Evidence of Intermolecular Forces

The phenomenon that serves as evidence of the presence of intermolecular forces between the molecules of a substance is 2) Смачивание (Wetting).

Wetting is a phenomenon that occurs due to intermolecular forces. When a liquid comes into contact with a solid surface, the degree to which the liquid spreads out or wets the surface is determined by the balance between adhesive forces between the liquid and the solid, and cohesive forces within the liquid itself.

This phenomenon demonstrates the presence of intermolecular forces, as the interaction between the liquid molecules and the solid surface is governed by these forces.

Therefore, the process of wetting provides evidence of the existence of intermolecular forces between the molecules of a substance.
