no its a chemical reaction
Dynamite exploding is a chemical change called combustion.
It is a chemical change.
Yes because it cannot change back.
Fuel exploding is a violent Chemical Reaction when fuel is reacted with atmospheric oxygen.
Dissolving and fizzing are physical processes.
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.
It is a chemical reaction because it changes and the change can't be revesed

It is usually a 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.
This is a physical change. Water can take on 3 forms, ice, gas, and liquid. These would be changes in state. Tearing, scratching, crushing, change in state, are all physical changes. Chemical changes must change the substance, not just the appearance. (i.e. Burning fire into ashes, fireworks exploding...)
