Is the statement true or false? If false, make the statement true.
1. An example of matter is heat emitted from burning wood.
2. The density of a gold bar is an example of a physical property.
3. The combination of H2O (g) to form elemental hydrogen and oxygen is an example of a physical change.
4. The ability of carbon to form carbon dioxide is an example of a chemical property.
5. The Si unit for mass is the gram.
6. A conversion factor contains a ratio of units.
7. Milk is a substance.
8. A student measures the mass of an object three times: 3.60 g, 3.90 g, and 3.75 g. The object actually has a mass of 3.75 g. Therefore, the student's measurements gave good precision.
