Burning a paper. Any change where you can't go back to the original item is a chemical change. You can't go from ashes back to a paper.
Crumpling a piece of paper is a physical change because it's still a piece of paper.
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
melting any metal is physical. rusting iron is chemical
All are examples of chemical changes

Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.

Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water
chemical
Anything that will create a new substance or change the chemical makeup of the substance. Burning, cooking, oxidizing, and other chemical reactions are examples.
melting any metal is physical. rusting iron is chemical
Physical changes can range from colour changes to change in tempricture.
A chemical change is a change that cannot be un-done; baking a pie would be a chemical change because you can't UN-BAKE a pie.
explosion of fireworks,cooking an egg
All are examples of chemical changes
