What takes place during a chemical change?
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
How heat energy can change the states of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
