4. Which ONE of the following statements is not correct? (a) In a physical change no new substance is formed, only the physical state of the material changes. (b) In a chemical change new substances are formed in a process that is not easily reversed and is usually accompanied by an energy change; Physical change, for example dissolving, cannot easily be reversed.
