A chemical change involve a change of composition.
a chemical change
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 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
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.

The chemical composition of a substance does not change when it undergoes a physical change.

Yes, when matter undergoes a chemical change, the composition of the matter changes at the molecular level. New substances are formed with different chemical properties than the original substances.

No, making wrapping for a present is a physical change, not a chemical change. The wrapping material undergoes a change in shape and form but its chemical composition remains the same.
Shortening melting is a physical change, not a chemical change or chemical property. When shortening melts, it undergoes a change in state from solid to liquid without any change in its chemical composition.

Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
