Transition Temperature

Transition temperature is the temperature at which a material changes from one crystal state (allotrope) to another. For example, when rhombic sulfur is heated above 96°C it changes form into monoclinic sulfur. When cooled below 96°C it reverts to rhombic sulfur.

In the case of ferroelectric or ferromagnetic crystals a transition temperature may be known as the Curie temperature.

Famous quotes containing the words transition and/or temperature:

    There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.
    Joseph Addison (1672–1719)

    This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.
    Henry David Thoreau (1817–1862)
