Answer 1

This is chemistry…
Nevertheless the answer is B. A physical change is a change from one state of matter to another; a chemical change results in a new substance being formed.

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.
