Gaseous osmosis is selective gas transport through a semipermeable membrane.

The Claim

The phenomenon of strongly attractive gases restricting degrees of freedom is scientifically recognized as gaseous osmosis.

Verified by Lenz · Sep 16, 2026

The Short Version

The stated phenomenon is not scientifically recognized as gaseous osmosis. Technical sources use that term for selective gas or vapor transport across a semipermeable barrier, typically driven by molecular exclusion or pressure, concentration, or vapor-pressure gradients. No cited evidence links gaseous osmosis to intermolecular attraction restricting degrees of freedom.

Caveats

The claim conflates membrane-mediated gas transport with effects associated with intermolecular attraction or non-ideal gas behavior.
No cited source states that strongly attractive gases restrict degrees of freedom under the name “gaseous osmosis.”
Some supporting materials are secondary, specialized, or repository documents, but the more direct technical evidence gives the same membrane-based meaning.
