Answer: Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.
Explanation: Physical change is a change in which there is no change in the chemical arrangement and thus there is no redistribution of atoms. No new substances are formed. There is only change in size, shape and phase etc.

Chemical change is a change in which there is change in the chemical arrangement and thus there is redistribution of atoms. which leads to formation of new substances.
