Particles in solids, liquids, and gases are all made up of the same fundamental building blocks: atoms and molecules. Here's how they are the same:

* Composition: All three states of matter are composed of atoms and molecules.

* Intermolecular forces: All three states of matter experience intermolecular forces, which are the attractive forces between molecules.

* Constant motion: The particles in all three states of matter are in constant motion. This motion is just different in each state.

Here's a summary table:

| State of Matter | Particle Arrangement | Particle Motion | Intermolecular Forces |

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

| Solid | Closely packed, highly ordered | Vibrate in fixed positions | Strong |

| Liquid | Closely packed, less ordered | Can move past each other | Moderate |

| Gas | Widely spaced, disordered | Free movement, high speed | Weak |

In conclusion: While the arrangement, movement, and strength of intermolecular forces are different in each state of matter, the underlying components (atoms and molecules) are the same.
