Which of the following is an example of a chemical change?
- A Rusting Iron
- B Melting ice
- C Breaking glass
- D Boiling water
That's Correct!
It's Wrong!
A chemical change occurs when a substance undergoes a transformation that alters its chemical composition. Rusting iron is a chemical change because iron reacts with oxygen and moisture to form iron oxide, a new substance. In contrast, melting ice, boiling water, and breaking glass are physical changes as they do not change the substance's chemical identity.
