Your teacher burns a piece of steel wool in class, demonstrating the chemical property, flammability. You are curious to see what other things can demonstrate chemical properties. Which of these does not demonstrate a chemical change?

I assume by "which" of these you're looking for an example. Water freezing into ice or water, or evaporation, the process of turning from liquid into vapor, would not be chemical changes.

Explanation:

These are physical changes because they do not form a new substance, a chemical change requires a change in the chemical makeup of the substance.
