No. Solid iodine goes directly from a solid to a gas in a process called sublimation, which is a kind of phase change, which is a physical change.

Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
if u heated them then its a physical change if u chucked another chemical on them its a chemical change if u did both then its a change of clothes
Is mixing powdered sugar and iodine a chemical change?
It's chemical because the iodine turns black instead of its usual red-purple color
A shiny black solid was heated and formed a purple vapour which on cooling became a black solid again Is this a physical or chemical reaction and explain?
This is a physical change. The solid is Iodine, which sublimes on heating to form gaseous Iodine. When cooled, it sublimes again to form solid Iodine. Since this change is only the change of physical states, and since there's no change in the chemical structure of Iodine, this is a physical change.
Is chemical change a black solid when heated changes into a purple gas?
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
Is purple color a physical and chemical change?
The color purple is a physical property, but if it appears during a chemical reaction, it is representative of a chemical change.
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.
Purple iodine vapor appears when solid iodine is warmed is that chemical or physical change?
Purple vapour appearing = physical
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
if u heated them then its a physical change if u chucked another chemical on them its a chemical change if u did both then its a change of clothes
What is iodine crystals sublime to make purple gas physical or chemical change?
It is a change of state and therefore a physical change.
When iodinebecome to purple gas describe chemical properties?
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.

Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation is a physical change, as ALL changes of state of matter (boiling, freezing, condensing, melting) are physical.
How does acidic potassium permanganate react with ki?
Permanganate(purple) becomes Mn2+(pale pink) and Iodide becomes Iodine.
Is purple color a physical and chemical change?
The color purple is a physical property, but if it appears during a chemical reaction, it is representative of a chemical change.
Is chemical change a black solid when heated changes into a purple gas?
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
What is the reaction of iodine on the endosperm of a maize seed?
Iodine gets in the 3D structure of the starch (which is the main ingredient of maize endosperm) and becomes purple.
