  "term": "Outgassing",
  "field": "Chemistry",
  "definition": "The release of adsorbed or absorbed gases from a material, typically occurring when the material is exposed to a vacuum or elevated temperature. This process can contaminate vacuum systems or alter the properties of the material itself. The rate of outgassing depends on the material's porosity and surface area.",
