The particles of a solid are closer together than those of a liquid or a gas. This is because the amount of energy in the system is less. If you take a solid and add enough energy (heat), you turn it into a liquid. The particles are moving faster than in the solid state and are bumping each other and that of any container . . . thus moving away from each other. This makes the volume increase . . .thus reducing the density. Add even more heat and you turn the liquid into a vapor which has particles moving the fastest of these three states of matter. These particles are then much farther apart, therefore, less dense.

Because the atoms are packed closer together in a solid than in a liquid or a gas. They also move around less than in a liquid or a gas. That said, solids are mostly empty space. It is the electron density that makes something feel "solid."

they don't. that's why wood floats on water. because water has a higher density than wood

Because their atoms are the closest together.

Do they??? Mercury (a liquid) is denser than wood (a Solid)

Not necessarily true for ice/water.

simply because the molecules are compressed. their atoms are more compact.
