Iodine is an element and its special property is sublimation, this is a physical change from solid iodine to gasous iodine with no liquid phase(or state) in between.
It is a Physical Process because, there is no chemical change in the Iodine. The only change that occurs is the change from solid to vapor state of the Iodine.
Iodine is a solid at 20 degrees Celsius.
The color of solid iodine is a dark purple.
Iodine melting is a physical change.
