It is a physical change because no new substance is formed, it is the other form of iodine.

Is iodine subliming a physical and chemical?
Sublimation of iodine (solid to gas without passing through liquid phase) is a physical change because the chemical composition of iodine remains the same during the process. The intermolecular forces between iodine molecules are overcome at certain temperature and pressure conditions, causing the solid iodine to directly convert into a gas.
Is dry ice subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
What is a physical change A fermenting grapes to produce wine B baking a cake C a tomato ripening D dry ice subliming E digesting a meal?
D. Dry ice subliming is a physical change. Chemically, it's still CO2.
What substances change from gas to solid?
Substances that change from gas to solid undergo a process called deposition. Examples include water vapor turning into snowflakes, carbon dioxide subliming into dry ice, and iodine subliming into solid crystals.
Iodine sublimes to iodine vapor is physical or chemical change?
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.
Is iodine melting a chemical or physical change?
Iodine melting is a physical change, as it does not alter the chemical composition of the iodine. It simply changes from a solid to a liquid state due to the input of heat energy.
Is subliming ice a chemical change?
No, subliming ice is a physical change where ice changes from a solid directly into a gas without melting into a liquid first. It is a phase transition process and does not involve any chemical reactions or changes in the chemical composition of the ice.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.
Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
At room temperature the element iodine is purple soild that easily becomes a gas why is the change in the iodine classified as a physical change?
Why does the food change purple when iodine is put in it.
Is iodine dissolves in alcohol a chemical or physical change?
When iodine dissolves in alcohol, it is a physical change because no new substances are formed. The iodine molecules are simply dispersed in the alcohol solution, but the chemical properties of iodine and alcohol remain the same.
