Physical change:-

• When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.

• Physical change is a temporary change.

• A Physical change affects only physical properties i.e. shape, size, etc.

Chemical change:-

• When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.

• A chemical change is a permanent change.

• Chemical change both physical and chemical properties of the substance including its composition.
