  "id": "MLC-T-CHM-003211",
  "term": "Dilatometer",
  "field": "Chemistry",
  "definition": "An instrument used to measure changes in the volume of a material as a function of temperature or pressure. It operates by detecting the expansion or contraction of a sample, often immersed in a fluid, within a precisely calibrated chamber. Dilatometry is employed to determine thermal expansion coefficients, phase transitions, and glass transition temperatures of polymers.",
