Explosions could be caused by a chemical reaction, or they could have a mechanical cause. It could even be nuclear. If a stick of TNT goes off, it's chemical, while a compressed gas cylinder with a failing weld that explodes while being filled is mechanical. A nuclear weapon is driven by nuclear reactions. All involve a rapid and violent release of energy. The thing that makes an explosion is the speed of the activity, whether it be chemical or mechanical. A high explosive anti-tank round is a chemical weapon, while a ballistic "spear" (perhaps made with depleated uranium) used to defeat modern armor is a mechanical weapon.
What else can I help you with?
Is the the explosion of fireworks a physical change?
Explosiveness (not oxploziveness!) is a property, not a change. But it is a chemical property.
Are fireworks an example of physical or chemical change?
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.
Is fireworks a chemical or physical change?
It is a chemical change because it has oxidation and combustion.Both. There's a rapid chemical change which liberates a lot of heat quickly and some of the material may become a gas, the physical change.Read more: When_firework_explodes_is_physical_change_or_chemical_changeNote: release of heat is not a physical change but only a consequence of a chemical change.
In a fireworks show the fireworks explode giving off thr heat and light.Is it a physical or chemical change.?
The explosion of fireworks is a chemical change. This occurs because the combustible materials in the fireworks undergo a chemical reaction when ignited, resulting in the production of new substances, such as gases and light. The release of heat and light is also indicative of this chemical reaction. Physical changes, in contrast, do not involve the formation of new substances.
Is fireworks physical change or chemical change?
chemical
Give examples of chemical change?
explosion of fireworks,cooking an egg

What different between chemical change and physical change?
A physical change stays the same like tearing paper A chemical change makes the substance something new like fireworks explode (fireworks change to explosion)

Is exploding of fireworks physical or chemical?
The explosion of fireworks is a chemical reaction. It involves the combustion of various chemical compounds within the fireworks to produce heat, light, sound, and colored displays. The reaction is initiated by a physical process, such as a fuse or electronic ignition, but the explosion itself is a result of the chemical reaction.

Are fireworks a chemical change or a physical change? Fireworks are a chemical change because once you lite it, it reacts to the fire.eat dodo doodadsdodo doodads

chemical
Is exploding of fireworks a physical or chemical change?
I guess it is a chemical change as the exploded fireworks cant be regained back which is possible in a physical change and not in a chemical change.
What is the chemical reaction involve in the explosion of fireworks?
Gun powder and kinetic energy
