Sublimation
Sublimation is the process in which a substance changes directly from a solid to a gas without passing through the liquid state. This occurs when the solid absorbs enough energy, typically in the form of heat, to break the bonds holding its particles together. A common example of sublimation is dry ice (solid carbon dioxide), which evaporates into carbon dioxide gas at room temperature. This process is used in various applications, such as freeze-drying food and in certain industrial processes. Sublimation is a fascinating physical phenomenon that highlights the different ways matter can change states.
