Why do fireworks have different colors?
Show answer & explanation
Answer: Different metal compounds
Flames burn at different temperatures — Wrong. While temperature affects brightness, specific colors come from chemical composition, not heat levels.
Different metal compounds ✓ — Correct! Different metals emit specific colors when heated. Copper makes blue, strontium makes red, barium makes green, sodium makes yellow. Firework makers carefully mix these compounds to create their colorful displays!
Colored paper wrappings — Wrong. Colors come from inside the firework, not external wrapping. Metal compounds burning create the light.
