| transition point [tran`zish·ǝn ´pȯint] ELECTROMAGNETISM A point at which the constants of a circuit change in such a way as to cause reflection of a wave being propagated along the circuit. THERMODYNAMICS Either the temperature at which a substance changes from one state of aggregation to another (a first-order transition), or the temperature of culmination of a gradual change, such as the lambda point, or Curie point (a second-order transition). Also known as transition temperature. |
