(a) Interpretation: The transformation from [1] to [2] from the given diagram should be labeled as physical change or chemical reaction . Concept Introduction: In any chemical reaction, new substances are produced by combining two or more substances with each other or by breaking down one substance into many. When change only occurs in the form or state of any substance, it is known as physical change and it does not cause a change in substance composition.
