Answer 1

Correct! Chemical changes involve the formation of new substances, while physical changes do not. Physical changes may include shifts in the phase of matter, such as melting or evaporating, and they can be reversed. Chemical changes, on the other hand, cannot be easily reversed and often involve the release or absorption of heat.
