chemistry of fireworks....what does this mean?
'Fireworks generate three forms of energy: sound, light and heat. That booming sound you hear after the explosion is from the quick release of energy, which causes the air to expand faster than the speed of sound, causing a shockwave.'
how can the air move faster than the speed of sound and cause a booming sound?
