Color physical or chemical

All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample). Chemical properties describe the characteristic ability of a substance to react to form new ….

Color changes indicate chemical change. The following reaction occurs: Fe +O2 → Fe2O3 Fe + O 2 → Fe 2 O 3. Physical: because none of the properties changed, this is a physical change.
