I Think Its Somethink To Do With heat
they both sublime, in which the solid particles will change directly into gas.
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.

To convert molarity to normality for iodine, you need to consider the valency of iodine in a reaction. Since iodine has a valency of 1 in most reactions, there is no change in converting molarity to normality for iodine. Therefore, 0.025M iodine remains the same when expressed in normality.
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
iodine
it's called sublimation
It would depend on how much iodine is present. The greater the mass the more particles there would be
Iodine can change it because iodine is poisonous
they both sublime, in which the solid particles will change directly into gas.
When powdered sugar is added to iodine, it forms a purple-black complex known as a starch-iodine complex. This reaction occurs because iodine reacts with the starch content in the powdered sugar, producing this distinct color change.
Why does the food change purple when iodine is put in it.
A compound containing sand and gold could be a mixture of the two substances, where the gold particles are mixed with the sand particles. If water and iodine are added to this mixture, the water could dissolve the iodine to form a solution, leaving the sand and gold particles unchanged.
magenta vapout
the movement is minimum because the particles in a solid, in this case shiny crystals of iodine, are tightly packed and therefore can not move alot.
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.
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.
