Mixing powdered sugar and iodine is a physical change, not a chemical change. In this case, the substances are simply being combined physically, without any new substances being formed. A chemical change would involve a reaction between the powdered sugar and iodine, resulting in the formation of new substances with different chemical properties.
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Chemical, When something changes in color, it is a sign of a 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.
Mixing iodine with cornstarch does not result in a chemical reaction. Instead, it forms a physical mixture in which the iodine molecules become trapped within the starch molecules, causing the mixture to change color. The iodine acts as an indicator of the presence of starch.
Its a physical change as there is no reaction.

physical because its a mixture and doesnt chemically combine
Mixing is not itself a chemical change. There could be one occurring as a result, but nothing you described indicated any kind of chemical change.
Mixing powdered sugar and iodine will not have any significant reaction, as iodine is not a strong enough oxidizing agent to react with the sugar. The two substances will likely remain as separate particles with the iodine coloring the sugar.
It depends on what you are mixing it with.
