Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.
In crystallography, the transition temperature is the temperature at which a material changes from one crystal state to another. [1] More formally, it is the temperature at which two crystalline forms of a substance can co-exist in equilibrium.

The Murrieta Hogbacks are underlain by Cretaceous granitic rocks of the Peninsular Ranges Batholith.On the north half of the hogbacks, by foliated biotite-hornblende tonalite and on the southern half by hornblende gabbro.
Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite.It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below.
White phosphorus (left), red phosphorus (center left and center right), and violet phosphorus (right) White phosphorus and resulting allotropes Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids.
Xenophagy (Greek "strange" + "eating") and allotrophy (Greek "other" + "nutrient") are changes in established patterns of biological consumption, by individuals or groups.. In entomology, xenophagy is a categorical change in diet, such as an herbivore becoming carnivorous, a predator becoming necrophagous, a coprophage becoming necrophagous or carnivorous, or a reversal of such changes.
