Both, sorta. The explosion itself is expanding hot gas, which is a purely physical reaction. However, most of the time, that's triggered by a chemical reaction to create the heat.

Are explosions a physical change or a chemical change?

Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.


Is explosive a physical change?

By explosion, you mean combustion I presume. Because combustion is a type of reaction, explosions are chemical changes.

This is a chemical property.


Why do explosions happen?

explosions happen because there is a chemical called acid that makes it explode


What is a reacts with oxygen is it physical or chemical?

Chlorine is a highly reactive agent thus this indeed is chemical.


What is the property of explosions?

Explosions are rapid chemical or physical reactions that release a large amount of energy in the form of heat, light, and pressure, often resulting in a shock wave. This sudden release of energy can cause significant damage to surrounding structures and can produce sound waves and shrapnel. Explosions can occur in various contexts, including chemical reactions, nuclear fission, and the detonation of explosives. Their intensity and effects depend on the type of material involved and the conditions of the environment.


What are explosions made off?

Explosions are typically made of a rapid release of energy in the form of heat, light, sound, and pressure. They occur when a sudden chemical reaction or physical force causes a rapid expansion of gases. The specific materials involved can vary greatly depending on the type of explosion.

Are exploding fireworks an example of a physical or chemical change?

Exploding fireworks are an example of a chemical change. The chemical compounds within the fireworks undergo a chemical reaction when ignited, resulting in a new substance being formed that releases energy in the form of heat and light.


Why is a explosion a fast chemical change?

Because explosions don't happen slowly


Is exploding a chemical change?

An explosion is the sudden release of a volume of compressed gas. The chemicals remain the same, so it is only a physical change.Note that the reaction resulting in an explosion may be a chemical change, but the resulting pressure changes are not.
