Answer:
physical change does not cause a substance to become a fundamentally different substance but a chemical change causes a substance to change into something chemically new. ... They are also physical changes because they do not change the nature of the substance.
Explanation:
Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter.
