C) Chemical changes involve formation of a new substance while physical change only impacts appearance or form.
Explanation:
The obvious difference between a chemical change and physical change is that in a chemical change new substances are produced while in a physical change, the form of the compounds are altered.
Most phase changes are products of physical changes. Such changes are easily reversible.
In a chemical change, a new kind of matter is formed. It is accompanied by energy changes.
