Similarities between Physical and Chemical Changes?

Answer

The biggest similarity between a physical and a chemical change is that the state of the reactants are changed. Also, both chemical and physical changes are always accompanies by the changes in the energy. Heat can be consumed and released in both types of changes, both physical and chemical. Also, another similarity is that new products are formed as a result of both of the reactions. Despite these similarities, the two changes are quite different from each other.
