Nucleation is a chemistry term. It can be used to describe, either the formation process of clouds, or the formation of crystals.
Nucleation is the process by which new crystal structures form in a liquid or gas, often triggered by the presence of impurities or tiny particles. It is an important step in the formation of various substances like snowflakes, clouds, and even certain types of crystals. Nucleation plays a crucial role in many natural and industrial processes.
