deszublimációja

Dezsublimációja is a Hungarian term that describes the process of a substance transitioning directly from the solid phase to the gaseous phase, bypassing the intermediate liquid phase. This phenomenon is the reverse of deposition, where a gas directly becomes a solid. While the more common term for this transition in English is sublimation, dezsublimációja specifically refers to the solid-to-gas transition in Hungarian.

This process occurs when the vapor pressure of the solid exceeds the surrounding atmospheric pressure. For a substance to undergo dezsublimációja, its molecules must gain enough kinetic energy to overcome the intermolecular forces holding them in a fixed lattice structure as a solid. This energy input is typically in the form of heat.

Common examples of substances that exhibit dezsublimációja include dry ice (solid carbon dioxide) and iodine. Dry ice, at standard atmospheric pressure, does not melt into a liquid but directly turns into gaseous carbon dioxide. Similarly, iodine crystals, when heated, vaporize directly without forming a liquid. The rate of dezsublimációja is influenced by factors such as temperature, pressure, and the specific properties of the substance. Understanding dezsublimációja is important in various scientific and industrial applications, including freeze-drying, purification techniques, and chemical reactions.
