Caption: Iodine sublimation and melting. Solid iodine being heated in a laboratory beaker, producing a purple gas and a purple liquid. Iodine at room temperature is a grey-black solid. Gentle heating below the melting point drives a solid-gas transition known as sublimation. Further heating results in the iodine melting (at 113 degrees Celsius). Iodine, found in seaweed and sea water, is an essential part of the diet.
