It depends on the explosion. Chemical ones need heat, or shock (like nitroglycerine) or a small blast to "set off" a charge (like the detonator in a 500 pound bomb). As far as a mechanical one, a mechanical trigger like a pin in a balloon or too much pressure in a compressed gas cylinder and the mechanical failure of the container due to overpressure will do the trick. In a fission nuclear weapon, forcing enough fissile material together with a chemical explosive and holding it together a split second to permit the chain reaction to build sufficiently will set it off. For a fusion weapon, a fission weapon will be needed to create the heat and pressure around the fusion material to cause it to fuse and go off.
An explosion of a firework requires heat to ignite the chemicals within the firework. Once ignited, the explosion of the firework releases light, sound, and heat energy as the chemicals burn and react.
Yes, a firework produces its own light through a chemical reaction inside the firework's shell. The explosion of the firework ignites various compounds that create colorful light displays in the sky.
For an aerial shell, rule of thumb is about 50-80 feet per shell inch.
When a firework "reports," it means that it makes a loud noise, typically a bang or explosion, as part of its visual display. This is a common effect in fireworks shows, and it adds excitement and spectacle to the overall presentation.
No, a firework is not a gas. It is a solid object that contains various chemicals and elements that produce a visual and auditory display when ignited. The reaction and combustion of these materials create the colorful explosion seen in fireworks.

black powder forces the stars out and ignites them.
Definitely a chemical change, The elements in the firework undergo very rapid combustion (burning) which is a chemical change.

Because you can't see the explosion during the day.

The design of the firework, including the type and arrangement of the materials inside, determines the pattern of its explosion. Factors such as the chemical composition, timing of the ignition, and shape of the casing play a role in creating specific effects like bursts, stars, or trails. Timing mechanisms and choreographed sequences also contribute to forming patterns in a firework display.
People set off fireworks by lighting a fuse attached to the firework. The lit fuse ignites the gunpowder inside the firework, creating an explosion that propels the firework into the sky. The firework then bursts open, displaying a colorful and dazzling light show.
An air bomb in fireworks is a type of firework that produces a loud explosion without a visible effect in the sky like other types of fireworks. It is designed to create a booming sound that reverberates through the air, adding excitement and intensity to a fireworks display.
