| Physical Change | Chemical Change |
| When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged. | When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances. |
| Physical change is a temporary change. | A chemical change is a permanent change. |
| A Physical change affects only physical properties i.e. shape, size, etc. | Chemical change both physical and chemical properties of the substance including its composition |
| A physical change involves very little to no absorption of energy. | During a chemical reaction, absorption and evolution of energy take place. |
| Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. | A few examples of chemical change are digestion of food, burning of coal, rusting, etc. |
| Generally, physical changes do not involve the production of energy. | Chemical changes usually involve the production of energy (which can be in the form of heat, light, sound, etc.) |
