  "id": "MLC-T-CHM-001998",
  "term": "Chimney effect",
  "field": "Chemistry",
  "definition": "The natural upward movement of air or gases within a vertical conduit, such as a chimney or vent, driven by differences in temperature and density. Hotter, less dense air inside the conduit rises, creating a pressure differential that draws in cooler, denser air from below. This phenomenon is also known as stack effect.",
