  "id": "MLC-T-MET-006198",
  "term": "Heat of vaporization",
  "field": "Meteorology and atmospheric science",
  "definition": "The latent heat absorbed by a substance when it changes from a liquid state to a gaseous state at a constant temperature. This energy input is necessary to overcome intermolecular forces and is a fundamental process in the Earth's water cycle. For water at 100 degrees Celsius, this value is about 2260 kilojoules per kilogram.",
