Explanation:

1. Fireworks exploding involves chemical reactions that produce heat, light, and sound, so it's a chemical change.
2. Squeezing oranges to make juice only changes the physical state of the oranges, separating the liquid from the solid parts without changing the chemical composition, so it's a physical change.
3. Frying an egg causes proteins in the egg to denature due to heat, which is a chemical reaction changing the chemical structure of the egg, so it's a chemical change.
