Tiivistymä

Tiivistymä is a Finnish term that denotes the act or result of becoming dense or compact. It derives from the verb tiivistyä and is used across scientific and everyday language to describe processes in which particles or substances become more closely packed, or the state that results from such a change.

In physics and chemistry, tiivistymä often refers to condensation, the transformation of a gas into a liquid or solid as energy is removed or pressure increases. It can describe the appearance of a condensed phase during phase transitions or the formation of dense aggregates in solutions or suspensions.

In meteorology and common usage, tiivistymä describes the condensation of water vapor, producing dew on surfaces, fog, or clouds when atmospheric conditions favor the formation of droplets.

In materials science and engineering, tiivistymä refers to densification and compaction of powders and porous materials during processing, such as pressing, sintering, or hot isostatic pressing, leading to reduced porosity and increased strength.

The term is versatile, and its precise meaning depends on the discipline. Synonyms in English vary with context and include condensation, densification, or compaction. Related Finnish terms include tiivistyminen (the process of becoming dense) and tiivis (dense).
