I don't copy from google, so this is my answer
i) chemical change – a process in which chemical bonds are broken or created to make a new substance physical change – a process in which a substance changes its state of matter, but chemical bonds stay intact.
ii) Physical change brings a change in appearance whereas a chemical change brings a change in appearance and chemical bonds.
iii) n a physical change, the material involved in the change is structurally the same before and after the change. Types of some physical changes are texture, shape, temperature, and a change in the state of matter. A change in the texture of a substance is a change in the way it feels.
Hope this helps!
