Morphology

outgas = gas (transparent) = out + gas

Clear productive formation: 'out-' + 'gas' meaning 'to release gas from a material'; the technical context does not obscure the derivation.

Etymology

Outgas comes from the parts out- 'out' and gas 'air or vapor', like a new bottle or plastic that slowly lets its fizz or smell go out. So in science it means a solid or liquid releases gas into the air, often when it is warmed or left in a vacuum.
