Both are chemical changes.
Explicação
The question is asking about the commonality between two processes: boiling sugar to make caramel and a copper statue turning green. 1. Boiling sugar to make caramel: This is a chemical change. When sugar is boiled, it undergoes a chemical reaction that changes its structure and properties, resulting in caramel. This change is not reversible, which is a characteristic of a chemical change.2. A copper statue turning green: This is also a chemical change. The green color on a copper statue is due to a chemical reaction between copper and the elements in the air, such as oxygen and moisture. This reaction forms a layer of copper carbonate, which is green in color. This change is also not reversible, which is another characteristic of a chemical change.Therefore, the commonality between these two processes is that both are chemical changes.
