A solution is a material not a change; dissolving is a physical process.
A solution does not have a chemical change, but it does have a physical change in state.
Physical
The decomposing of a solution can be either physical or chemical, depending on the nature of the process. Physical decomposition involves a change in appearance or phase without altering the chemical composition of the solution. Chemical decomposition, on the other hand, involves a breaking down of the chemical bonds in the solute molecules, resulting in the formation of different substances.
Chemical, if it dissolves in a solution such is acid. Physical if one mean dissolves like disintegrates.
Dissolving
Dissolving is a physical change.
it is a chemical change
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.
The chemical and physical properties are changed.
Heating a salt solution is a physical change, not a chemical change. When a salt solution is heated, the water in the solution may evaporate, or the solution may become more concentrated, but the chemical composition of the salt (sodium chloride) remains unchanged. This process only alters the physical state or the concentration of the solution, without any new substances being formed.

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.
