Physical change is a change in shape of an object but not with its chemical component. While chemical change is a change wherein a new substance is formed.

1. Physical change
2. Physical change
3. Chemical change - to be able to heal the bone completely there would be a            chemical reaction that'll occur
4. Chemical change - the burnt paper turns into ash
5. Physical change
6. Physical change
7. Chemical change - the chicken would have a new form (fried)
8. Chemical change - the chemical component changes and the rusting cannot be         changed back again, so it's a new form
9. Physical change
10. Chemical change - turns into ash
