Chapter 1 Test - Introduction to Matter

- The SI unit of mass is the kilogram (kg).
- The SI unit of volume is the cubic meter (m^3)
- You can determine the density of a sample of matter by dividing its mass by its volume.

- A substance that undergoes a physical change is still the same substance after the change.
- Unlike a physical change, a chemical change produces new substances with new and different properties.
- Every chemical and physical change in matter includes a change in energy.
