Sublimation temperature is the specific temperature at which a substance changes directly from a solid to a gas without passing through the liquid phase. This phase transition occurs under certain pressure conditions, typically at low pressures or in a vacuum. The sublimation temperature varies depending on the material and the surrounding pressure. A well-known example is dry ice (solid carbon dioxide), which sublimates at \(-109.3 \; F^\circ \; (-78.5 \; C^\circ)\) under atmospheric pressure. Sublimation is used in various industrial and scientific processes, such as freeze-drying, purification of chemicals, and fabrication of certain materials. Understanding the sublimation temperature of a substance is important for storage, handling, and processing in controlled environments.
