physical changes
================

when matter changes it observable properties we can say it has undergone a physical change.physical change is a type of charge where the physical properties of matter change.A change of state of matter, change in color, odor, solubility, etc. all are examples of physical change. During a physical change, neither the composition nor the chemical nature of matter is changed. During this change, molecules rearrange themselves without affecting the internal composition. A physical change doesn’t affect the chemical property.


Chemical change:
================
Chemical change is a type of change where the chemical properties of matter change. It is commonly called a chemical reaction. A chemical reaction results in a new product. During a chemical change, bonds between the molecules break and the composition of the substance change. In other words, chemical change leads to the breaking and making of bonds. , rusting, fermentation, etc. are few examples of chemical change.

I hope it will help you...

Answer 2

Those changes which includes the changes in physical properties a substance is called physical change.
Ex- change in shape,size ,colour etc

On the other hand, those changes which includes the changes in which a substance rects to form a entire new product which is not capable of changing in its original state are known as chemical changes.
Ex- rusting of iron, digestion, ripening of fruits etc.
