Hysteresis

  "id": "MLC-T-CHM-005559",
  "term": "Hysteresis",
  "field": "Chemistry",
  "definition": "The phenomenon where the state of a system depends not only on its current conditions but also on its past history. In chemistry, this is observed when a property, such as adsorption or magnetization, follows a different path during increase and decrease of an external parameter. An example is the difference in adsorption and desorption isotherms for porous materials.",
