How can the appearance of a substance change without it becoming a different substance?

Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

When the chemical composition of a substance remains does not change, the change in appearance will not lead to change in the properties of the substance.

What is chemical composition?

Every substance is characterized by its chemical composition, which is defined as the proportion of atoms present in the molecules of a substance.

A substance will become different only if there are changes in the chemical composition, but appearance's changes do not lead to change in the entire substance.

Hence, when the chemical composition remains constant, a change in appearance does not lead to making the substance completely different.
