ALLOTROPY

(Yunanca köken — orijinale bakınız.) A term used by Berzelius to designate the property belonging to certain substances of exhibiting variable characters at different temperatures, especially as relates to colour, texture, solubility, .: thus sulphur is usually yellow and brittle; but if fused at a high temperature, and poured into water, it becomes brown and viscid, j The characters of phosphorus may also be remarkably changed by temperature, though its nature, as well as that of sulphur, remains the same.
