  "id": "MLC-T-CHM-011644",
  "term": "Surface excess enthalpy",
  "field": "Chemistry",
  "definition": "The enthalpy associated with the formation of an interface, representing the difference in enthalpy between the actual system with an interface and a hypothetical system without an interface. This quantity accounts for the energy and pressure-volume work changes at the surface. It is measured in joules per unit area.",
