Transformation of solid iodine to the gaseous state at room temperature.
The heaviest of the stable halogens it exists as a lustrous purple black non metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees celsius and boils to a violet gas at 184 degrees celsius however it sublimes easily with gentle heat resulting in a widespread misconception even taught.
The temperature of the sample remains constant while the ice melts.
The molecular lattice contains discrete diatomic molecules which are also present in the molten and the gaseous states.
Iodine is a chemical element with the symbol i and atomic number 53.
The process of transition of a substance directly from its solid phase to gaseous phase without going through the liquid state is called sublimation.
Results in the reaction i2.
