| Volume | The amount of space an object takes up. |
| Pressure | The amount of force exerted on a given area of a surface. |
| Boyle's Law | Gas at a fixed temperature. As the volume decreases the pressure increases. |
| Charles's Law | Gas at a constant pressure. As the temperature increases the volume of the gas increases. |
| Barometer | Instrument which measures atmospheric pressure. |
| Celsius | SI unit of measure for degrees of temperature. |
| Compressible | The ability to make smaller |
| Homogeneous | Appears as one solution |
