WebCrystallization is a natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or gas. This can be caused by a physical change, such as a temperature change, or a chemical change such as acidity. Does crystallization absorb or release energy? And the breaking of bonds REQUIRES energy. WebHow does the crystallization process occur? The crystallization process consists of two major events: Nucleation – Molecules gather together in clusters in a defined manner. Clusters need to be stable under current …
