It does change its physical look but it does not change chemically.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
A chemical property involves the production of a new substance. This occurs when a substance undergoes a chemical reaction that results in the formation of one or more different substances with different chemical compositions.
A reactant

A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.

This is called reaction rate.
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.
The chemical composition of a substance does not change when it undergoes a physical change.
