The three states of matter, solid, liquid, and gas, have several things in common:

* They are all made up of atoms and molecules. These particles are just arranged differently in each state.

* They all have mass and take up space. This means they have volume.

* They all have energy. The amount of energy determines the state of matter.

* They all can change state. This is called a phase change and happens when energy is added or removed. For example, water can freeze (liquid to solid), melt (solid to liquid), boil (liquid to gas), or condense (gas to liquid).

Here's a table summarizing the differences:

| Property | Solid | Liquid | Gas |

|---|---|---|---|

| Shape | Definite | Indefinite (takes shape of container) | Indefinite (takes shape of container) |

| Volume | Definite | Definite | Indefinite (expands to fill container) |

| Density | High | High (less than solid) | Low |

| Compressibility | Low | Very low | High |

| Particle arrangement | Closely packed, regular pattern | Closely packed, irregular pattern | Widely spaced, random movement |

| Movement of particles | Vibrate in fixed positions | Slide past each other | Move freely and randomly |
