  "id": "MLC-T-CHM-012717",
  "term": "Work of cohesion per unit area",
  "field": "Chemistry",
  "definition": "The reversible work required to separate a column of a pure liquid into two free surfaces, each with the same area as the original cross-section. It represents the energy needed to overcome the cohesive forces within the liquid. This quantity is equal to twice the surface tension of the liquid.",
