Difference Between Physical And Chemical Change

6 Differences Between Physical And Chemical Change

S.NO.	Physical Change	Chemical Change
1.	Composition: Physical changes do not alter the chemical composition of a substance.	Chemical changes alter the chemical composition.
2.	Energy: Physical changes do not typically involve a significant change in energy.	Chemical changes involve a change in energy.
3.	Reversibility: Physical changes are often reversible.	Chemical changes are typically irreversible.
4.	Observability: Physical changes are often visible or easily detectable.	Chemical changes may not be easily observable.
5.	Product formation: Physical changes do not involve the formation of new products.	Chemical changes involve the formation of new products.
6.	Conservation of mass: Not necessarily for physical changes.	Conservation of mass: The law of conservation of mass holds for chemical changes.
