Answer 1

Although the Statue of Liberty is made of copper (originally an orange-brown color), it is green because the copper has interacted with substances in the air to form new substances with different properties. This is an example of a B. chemical change.
That is because chemical change occurs when certain substances change their properties when they interact with other substances. This is why the color of copper changed, while its physical properties stayed the same.
