A process of heating a chamber or equipment to extremely high temperatures to remove gases and contaminants from its surfaces.
Compound of 'bake' (from Old English 'bacan') and 'out' (from Old English 'ūt'), combining the cooking process with the directional particle to describe expelling materials through heat.
Scientists use bakeouts on spacecraft and vacuum chambers to ensure there's nothing floating around that could ruin experiments—it's like giving equipment a really thorough cleanup just by turning up the heat!
