Let's break down these questions about physical and chemical properties:**Understanding Physical and Chemical Properties*** **Physical Properties:** These are characteristics that can be observed or measured without changing the substance's chemical composition. Examples include color, density, melting point, boiling point, and hardness.* **Chemical Properties:** These describe how a substance reacts with other substances or how it changes its chemical composition. Examples include flammability, reactivity with acids, and the ability to rust.**Answering the Questions**1. **Which of the following is a physical property?** * **(c) Melting point** is the correct answer. Melting point is the temperature at which a solid changes to a liquid, a change in state without altering the substance's chemical makeup.2. **Which of the following is a chemical property?** * **(c) Ability to burn** is the correct answer. Burning involves a chemical reaction (combustion) that changes the substance's composition.3. **Which process involves a chemical change?** * **(c) Rusting of iron** is the correct answer. Rusting is a chemical reaction where iron reacts with oxygen and water to form iron oxide (rust), a new substance.4. **What happens during a chemical change?** * **(b) The chemical identity of the substance changes** is the correct answer. Chemical changes involve the formation of new substances with different properties.5. **Which of the following is a chemical property of wood?** * **(c) Its ability to burn** is the correct answer. Burning wood is a chemical reaction that changes the wood's composition.6. **Which of the following describes a physical change?** * **(c) Tearing a piece of paper** is the correct answer. Tearing paper only changes its shape and size, not its chemical composition. **Key Takeaways*** Physical changes are temporary and reversible (like melting ice).* Chemical changes are permanent and involve the formation of new substances (like burning wood).
