Is there really a difference between a chemical change and a physical change?

Yes? A total difference.

I like how my teacher explained it once: A physical change is when you change how something is not what something is. Like when you crush a can that’s a physical change. When water becomes ice that is a physical change, since ice isn’t a different molecule than a water molecule.
Chemical changes happen when molecules change structure or something new is produced. When you burn wood, you produce ash and carbon dioxide. Or like how when iron rusts it oxidizes. Those are chemical changes.

Yes. A chemical change involves a variation in the chemical makeup or structure.

A physical change is a change in shape alone.

If a piece drops off, that’s a physical change. It is still the same object, it’s chemistry hasn’t changed, it’s just missing a piece. If the chemistry changes (like Allie said, burning, oxidizing, etc.) it’s a chemical change.

Physical change can thought as the change of objects dimension, area and volume.

Chemical change involves change of elements in a body. Natural elements can be found on periodic table. Chemical change is due to the substance undergoing a process which can be combustion, reduction, oxidation, hydrogenation, hydration, dehydration etc . you will know more when you learn chemistry in school.
