| Mass | The amount of matter in an object/substance. |
| Volume | The amount of space an object/substance takes up. |
| Density | How compacted the mass is within in object/substance. |
| Solids | The atoms are compacted together and can barely move (may vibrate). |
| Liquids | The atoms move freely and take up space of whatever container they are in. |
| Gases | The atoms are free and moving very quickly. |
| Matter | Any substance that has mass and takes up space. |
| Formula for density: | Density = Mass / Volume |
| Mass is measured in... | grams |
| Condensation | When gas is cooled and turns into a liquid. |
| Evaporation | Process of turning a liquid into a gas. |
| Melting | When a solid is heated to the point its particles become so active they can no longer hold their shape. Solid to a liquid. |
| Freezing | Liquid turning into a solid. |
| Thermal energy | is produced when a rise in temperature causes atoms to move quickly and collide with each other. |
| Convection | Heat transferred when fluids are circulated. |
| Conduction | Heat transferred between two objects through direct contact. |
| Radiation | Heat transferred between two objects with NO contact. |
| Kinetic Energy | Energy of an object in motion. |
| Potential Energy | Stored energy of an object due to its position. |
| Speed Formula | Speed = Distance / Time |
