In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one or several phase transitions into less ordered states.

In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one or several phase transitions into less ordered states.

在凝聚态物理学中，系统通常在低温下有序; 在加热时，它们经历一个或几个相变进入无序状态。

Examples for such an '''order-disorder transition''' are:

Examples for such an '''order-disorder transition''' are:

* the melting of ice: solid-liquid transition, loss of crystalline order;

* the melting of ice: solid-liquid transition, loss of crystalline order;

 

* the demagnetization of iron by heating above the [[Curie temperature]]: ferromagnetic-paramagnetic transition, loss of magnetic order.
