Why the particales in solids are tightly packed?

Answer 1

Because only the particles are packed together like that the solid can have define shape and volume. If they not packed together that are liquid.So we can use this point (the particles are packed together) to know what is that? Solid, Liquid or Gas. ---- The particles of a solid are packed tightly together, the particles of a liquid can move around but are still touching each other, and the particles in a gas are free to wizz around.

Answer 2

In a solid, particles are still constantly moving (Look up Kinetic Theory for more information) but are locked into a specific structure. So instead of atoms or molecules moving around and bumping into each other, they vibrate while remaining in the same area. (Electrons, protons and neutrons [sub-particles] can still move around in the atom, but again, the atoms are locked into a structure specific to that substance.

Answer 3

Particles in solids are tightly packed due to strong intermolecular forces, such as electrostatic forces, that keep the particles closely bound together. These forces prevent the particles from moving freely past each other, resulting in a fixed and organized structure characteristic of solid materials.

Answer 4

Because it is hard?
