34 Chemical and physical changes are alike in some ways and different in others. They are different because in a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.Also with physical change the identity of it stays the same. For chemical change it is different, it changes the entire identity of it. Physical changes’ combinations of molecules result in mixtures, But it is different for chemical changes’ there combinations/Reactions of molecules result in products. Physical and chemical changes are alike because they are both types of changes that can occur in various forms of matter. Both types of changes cause alterations to the original matter involved. In Conclusion this is how chemical and physical changes are alike and different.
