3. Sand being washed out to the sea from the beach is a chemical change: **False** (It is a physical change.)
4. Combining hydrogen and oxygen to make water is a physical change: **False** (It is a chemical change.)
5. When ice cream melts, a chemical change occurs: **False** (It is a physical change.)
6. Breaking up concrete is a physical change: **True**
7. Acid rain damaging a marble statue is a physical change: **False** (It involves a chemical change; the marble reacts with acid.)
8. Burning wood is a physical change: **False** (It is a chemical change.)
9. A physical change the makeup of matter is changed: **False** (In a physical change, the makeup of matter does not change; the substance remains the same.)
