Question

why does rocket make sound when it goes in the sky?

Answer 1

It’s easy to assume that the explosion of the gunpowder is behind the sound and that’s it. But it isn’t quite as simple as that since different sound effects require a bit more chemistry.
Furthermore, the explosion of the firework isn’t the only occasion for the sound to make presence. For example, when you shoot certain types of fireworks, such as rockets, you’ll hear the whistling sound as the firework goes up and then a bang as it explodes.

Answer 2

U know that rocket launches into space with a great explosion so this high pressure of explosion creates sound.
