Haihduttua

Haihduttua is a Finnish term derived from the verb haihduttaa, meaning to evaporate or to vaporize. It functions as the past passive participle of haihduttaa and is used to describe something that has undergone evaporation. In scientific and technical Finnish, haihduttua can appear as an attributive or predicative form in phrases referring to an substance or material that has already evaporated.

The related noun haihdutus denotes the process of evaporation, while haihduttaa expresses the act of causing evaporation. The form haihduttua is typically encountered in formal or descriptive contexts, including scientific writing, where it helps specify the state of a liquid after the evaporation process. The term sits within the broader lexical family around phase changes and drying techniques.

In its scientific sense, evaporation is the phase transition from liquid to vapor that occurs when molecules at the liquid surface gain enough energy to overcome intermolecular forces, often below the liquid’s boiling point. Rates of evaporation depend on temperature, pressure, surface area, airflow, and the liquid’s volatility and vapor pressure. Evaporation is central to applications such as drying processes, distillation, and desalination, as well as natural processes that contribute to atmospheric humidity.
