It is the detonator or fuse which is attached to the shell! sometimes some delays after explosions are made with help of binders or delay fuses.
Yes, potential energy is used in fireworks. When the fireworks are ignited, chemical potential energy is converted into thermal energy, which causes the fireworks to explode and create light and sound.
Either somebody shoots at the star. Or kills the star turning it into a supernova.
It doesn't explode it sparks rigid metal(notched metal) causes flint to spark when hit
There are pressurised gases in the canister. The heat causes the canister to explode.
Manganese dioxide is a catalyst for the decomposition of hydrogen peroxide.
Yes, potential energy is used in fireworks. When the fireworks are ignited, chemical potential energy is converted into thermal energy, which causes the fireworks to explode and create light and sound.
The match provides the initial flame to ignite the campfire. As the match burns, it ignites the surrounding kindling or material, which then continues to burn and spread to larger pieces of wood, creating a sustainable fire.
In fireworks, the atoms undergo rapid oxidation and release energy in the form of heat and light. Different atoms and molecules produce different colors when they are excited and emit light. The intense heat from the reaction causes the atoms to move rapidly, creating the explosion effect.
That's how they spread their seed.
the wire that heats blows
Either somebody shoots at the star. Or kills the star turning it into a supernova.
The loud bang sound during fireworks displays is caused by the rapid expansion of gases inside the fireworks shell when it explodes.
No, low pressure in a tornado does not cause buildings to explode. That is a common myth.
there are two chemicals i fireworks stars and commets then to get colours you etheir add magnisium or sulpher oxide by the way im 13
Activation of a fault during an earthquake.
Gasses in the atmosphere are given some energy (activation energy), this energy is used for the activation of the explosion. As a few gas particles react, they then have higher energy and as they collide into other air particles it causes them to react. This happens rapidly and thus an explosion occurs. I think. Think of it as an exothermic reaction, but uncontroled.
The same with beans, they start to expand in too much heat and eventually explode.
