kaasumaisissa

Kaasumaisissa is a Finnish term used to describe matter in the gaseous state or conditions characterized by gas-like properties. The expression functions as a plural inessive form of the adjective kaasumainen, meaning gaseous, and is typically found in scientific or technical Finnish when referring to multiple substances or multiple aspects of gas-phase conditions.

Etymology and usage: The root kaas-u- comes from kaas u (gas), combined with the adjectival suffix -mainen to form kaasumainen (gaseous). The endings -i- + -ssa/-issa mark the inessive case, with -ssa indicating singular and -issa indicating plural. Thus kaasumaisissa literally means “in gaseous conditions/states” and is usually part of a larger phrase such as kaasumaisissa olomuodoissa (in gaseous states) or kaasumaisissa olosuhteissa (in gaseous environments).

Context and examples: The term appears mainly in chemistry, physics, and engineering literature when discussing phase behavior, reactions, or processes occurring in the gas phase. Example usages include: Kaasumaisissa olomuodoissa aineen lämpötilan ja paineen vaikutus differoi toisistaan kuin nestemäisessä tai kiinteässä olomuodossa. Kaasumaisissa olosuhteissa reaktioasteet voivat olla suurempia, ja molekyylien vuorovaikutukset vähäisempiä. The phrase helps distinguish gas-phase phenomena from those in solid or liquid phases.

Related terms: kaasumainen (gaseous), kaasumaisuus (gas-like character), olomuoto (state of matter), olosuhteet (conditions).
