Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut

A change is said to be physical if it's shape, size or texture changes after a process. Eg: melting of ice
If it's a chemical change a new substance will be formed. Eg rusting of iron.
