Describe the density of particles in each state of matter

In solids, the particles are very compact with a fixed position, defining its shape.

In liquids, the particles have a little more space but are still close together, the position is not fixed, the liquid takes shape of its container.

In gasses, the particles are not close at all and move rapidly and freely, it does not take ANY shape.
