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.
Anything chemical , including oxygen, reacting with anything else is a CHEMICAL change. So Rust, is an oxide of iron. It has been formed by the chemical change of iron reacting with oxygen.
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.
A negative change in enthalpy in a chemical reaction can lead to the release of heat energy. This can result in temperature increases, potential hazards like fires or explosions, and changes in the physical properties of substances involved in the reaction.
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Chemical broooooooooooooooo niga
chemical
Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
This is a chemical property.
By explosion, you mean combustion I presume. Because combustion is a type of reaction, explosions are chemical changes.
explosions happen because there is a chemical called acid that makes it explode
Anything chemical , including oxygen, reacting with anything else is a CHEMICAL change. So Rust, is an oxide of iron. It has been formed by the chemical change of iron reacting with oxygen.
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.
A physical change
Because explosions don't happen slowly
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.
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.
