  "term": "Specific surface area",
  "field": "Chemistry",
  "definition": "The total surface area of a material per unit of its mass or volume. It quantifies the extent of the exposed surface of a substance, which is particularly relevant for porous materials or finely divided powders. This property is commonly measured using gas adsorption techniques, such as the Brunauer-Emmett-Teller (BET) method.",
