outgas
Emit trapped gases
To outgas is to release trapped gases from a solid material, typically under heat or vacuum conditions.
New plastics, foams, and building materials outgas volatile compounds—that new car smell is outgassing from interior components.
Spacecraft must outgas before launch to prevent contamination in space.
The noun is outgassing.
