Answer

Brief Explanations:

Chemical changes are characterized by the formation of new substances and indicators like temperature change, light production, and color change. Size and movement are physical - change related factors. In fireworks, a chemical reaction occurs when they explode. Temperature change happens due to the exothermic nature of the reaction. Light is produced as energy is released in the form of photons during the reaction. Color change is due to different metal salts in the fireworks that emit specific colors when heated.

Answer:

  • B. Temperature change
  • D. Light production
  • E. Color change
