Let's evaluate each statement one by one:
1. **Acid rain damaging a marble statue is a physical change.** - **False**. While the physical surface of the statue may be altered (like erosion), the acid rain can cause a chemical reaction that changes the composition of the marble (calcium carbonate) into a soluble compound.
2. **When ice cream melts, a chemical change occurs.** - **False**. Melting ice cream is a physical change; the composition of the ice cream remains the same (it's still ice cream).
3. **Breaking up concrete is a physical change.** - **True**. Breaking concrete changes its form and size but does not change its chemical composition.
4. **Combining hydrogen and oxygen to make water is a physical change.** - **False**. This is a chemical change, as the hydrogen and oxygen react to form a new substance, water.
5. **Changing the size and shapes of pieces of wood would be a chemical change.** - **False**. This is a physical change; the wood remains wood regardless of its size or shape.
6. **Burning wood is a physical change.** - **False**. Burning wood is a chemical change because it transforms the wood into ash, smoke, gases, and other substances.
7. **Sand being washed out to sea from the beach is a chemical change.** - **False**. This is a physical change; the sand's composition does not change when it is moved.
8. **Evaporation is a physical change.** - **True**. Evaporation changes the state of matter (from liquid to gas) but does not change the chemical composition of the liquid.
9. **In a physical change, the makeup of matter is changed.** - **False**. In a physical change, the makeup of the matter (its chemical composition) remains the same; only the form or appearance changes.
In summary:
1. False
2. False
3. True
4. False
5. False
6. False
7. False
8. True
9. False
