What describes a chemical change? bending a wire burning paper melting ice freezing water

A **chemical change** involves a process where substances are transformed into new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds, resulting in a change that is often not easily reversible. Let's examine each of the options you've provided: 1. **Bending a wire** - **Type of Change:** *Physical Change* - **Explanation:** Bending a wire alters its shape but does not change its chemical composition. The material remains the same before and after bending. 2. **Burning paper** - **Type of Change:** *Chemical Change* - **Explanation:** Burning paper involves a chemical reaction with oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. This change is not easily reversible. 3. **Melting ice** - **Type of Change:** *Physical Change* - **Explanation:** Melting ice changes its state from solid to liquid but does not alter the chemical composition of water (H₂O). 4. **Freezing water** - **Type of Change:** *Physical Change* - **Explanation:** Freezing water changes its state from liquid to solid without changing its chemical structure. **Conclusion:** Among the options listed, **burning paper** is the process that describes a **chemical change**.
