Explosions are typically classified as a chemical reaction. Chemical explosions involve a rapid release of energy due to the breaking and forming of chemical bonds in a highly exothermic reaction.
By explosion, you mean combustion I presume. Because combustion is a type of reaction, explosions are chemical changes.
A physical change
Physical change of the paint, not the door.
it is a chemical change
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
An acid is a chemical compound, not a physical or chemical change.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Chemical broooooooooooooooo niga
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
