The chemical composition of a substance does not change when it undergoes a physical change.
It does change its physical look but it does not change chemically.

no
All substances have physical changes.

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.
A substance that undergoes a physical change is water when it freezes into ice. This process changes the state of the water from liquid to solid without altering its chemical composition. Similarly, when ice melts back into water, it undergoes another physical change. Other examples include the melting of wax or the dissolving of sugar in water.
