Overgangstemperatuur

Overgangstemperatuur, often translated as transition temperature, refers to the specific temperature at which a substance changes from one state to another. This can involve changes in physical properties such as solid to liquid (melting point), liquid to gas (boiling point), or gas to liquid (condensation point). Beyond these common phase transitions, overgangstemperatuur can also describe the point where a material undergoes a significant change in its properties, even if it doesn't change its fundamental state of matter.

For example, in superconductivity, the overgangstemperatuur is the critical temperature below which a material loses all electrical resistance. Similarly, in magnetism, the Curie temperature or Néel temperature represents the overgangstemperatuur where a material loses its ferromagnetic or antiferromagnetic properties, respectively, becoming paramagnetic. Amorphous materials like glass have a glass transition temperature, which is not a sharp point but rather a range where their viscosity dramatically decreases, allowing them to flow over geological timescales. Understanding overgangstemperatuur is crucial in various scientific and engineering disciplines for predicting material behavior under different thermal conditions.
