Sublimation

Definition

Sublimation is the process by which a substance transitions directly from a solid to a gas without passing through the liquid phase. This phenomenon is important in various fields, including Islamic chemistry and alchemy, as it was used to describe the transformation of substances and the pursuit of creating pure materials.
