New substances are formed when matter undergoes a chemical reaction.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

When a substance undergoes a physical change, its identity remains the same, meaning its chemical composition does not alter. Examples of physical changes include melting, freezing, and dissolving, where the substance can typically return to its original state. The properties such as color, shape, and state may change, but the fundamental structure of the molecules remains intact.
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
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.

If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.

It does change its physical look but it does not change chemically.
