Morphology

degass = gas (transparent) = de + gas

This is a straightforward use of de- meaning 'remove' with 'gas', yielding the meaning 'remove gas from'.

Etymology

Degass comes from de- meaning 'remove' and gas, so it quite simply means 'remove gas'. A helpful image is opening a bottle of soda or letting air out of a balloon to let the bubbles escape, and in science to degass is to make a liquid or material release gas, often by heating.
