Color physical or chemical
If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Also, changes in temperature or color can be a consequence of both: physical and chemical changes. Leaves yellow as the result of a biochemical process, meaning it is a chemical reaction that occurs in a living thing. Even though some people think the change in the color of tree leaves in fall is an example of a physical change, the color change actually occurs because of chemical changes inside the leaf.

Physical properties are characteristics that can be observed without altering the composition of a substance. On the other hand, chemical properties involve changes in composition and are often associated with …Chemical changes, aka chemical reactions, result in creating one or more substances that differ from the original substances’ chemical identities compared to prior to the reaction.
