  "id": "MLC-T-CHM-010442",
  "term": "Roughness factor",
  "field": "Chemistry",
  "definition": "The ratio of the true surface area of a material to its apparent or geometric surface area. This factor quantifies the extent of microscopic irregularities and undulations on a surface. A higher roughness factor indicates a more irregular surface, which can influence properties such as adhesion, catalysis, and wettability.",
