Differences between physical and chemical changes?
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
Is fireworks a chemical or physical change?
It is a chemical change because it has oxidation and combustion.Both. There's a rapid chemical change which liberates a lot of heat quickly and some of the material may become a gas, the physical change.Read more: When_firework_explodes_is_physical_change_or_chemical_changeNote: release of heat is not a physical change but only a consequence of a chemical change.
Is boiling potatoes a chemical or physical change?

In a physical change some of the physical properties of the substance may be altered and the chemical composition?
No. In a physical change, the substance maintains its chemical composition.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.

chemical change :-)
Is hammering gold until it becomes flat a physical change or chemical change?
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
