The statement that is evidence of a
Concept introduction:
The changes in the state of the substance are referred to as physical changes. The physical changes do not involve the changes in the chemical structures of the substances. Chemical changes involve the changes in the chemical structure of the substances.
The chemical reaction can be identified by the changes shown below.
• Release of gas during the reaction.
• Formation of an insoluble solid in a solution.
• Change in color of the substance.
• Energy is either released or absorbed.
