When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
