Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?
This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.

Definitely a chemical change, The elements in the firework undergo very rapid combustion (burning) which is a chemical change.
When dynamite explodes is it an example of chemical change?
Yes, when dynamite explodes, it is an example of a chemical change. The chemical bonds within the dynamite molecules are broken and reformed during the explosion, resulting in the release of energy and the formation of new chemical compounds.
Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
