Property and Matter
| Term | Definition |
|---|---|
| Thermal energy | The kinetic energy of the moving particles in an object. |
| Solid | One of the four states of matter. It has structural rigidity and can resistance to changes of shape or volume. |
| Liquid | It is the only state of matter with a definite volume but no fixed shape. |
| Gas | Mostly invisible state of matter. It has variable volume and shape, adapting both to fit its container. |
| Plasma | less commonly known state of matter. It is very similar to gas. |
| Colloid | A solution that has particles ranging between 1 and 1000 nano-meters in diameter. Particles can stay evenly distributed. |
| Phase change | When a state of matter changes phase due to thermal change. |
| Particle | A tiny portion of matter. |
| Melting point | The temperature for a solid to melt into a liquid. |
| Freezing point | The temperature for a liquid to freeze into a solid. |
| Boiling point | The temperature for a liquid to evaporate into a gas. |
| Evaporation | The process of water turning into water vapor. |
| Condensation | The process of water vapor turning into water |
| Volume | Area of a 3-D shape. |
| Mass | The size and weight of an object. |
