uncondensable
Resists becoming liquid
Unable to be condensed—reduced in volume, compressed into denser form, or converted from gas to liquid.
In chemistry and physics, uncondensable gases resist liquefaction under given conditions of temperature and pressure: The uncondensable vapors were vented from the system.
The term appears in technical contexts involving distillation, refrigeration, and gas processing.
