Detailed explanation-1: -Particles in a solid or liquid move slower. and closer together when they are in an agglomeration.

Detailed explanation-2: -• Solid: Explain that in a solid, the particles are very attracted to each other so they are close together. The particles can move in their fixed positions but cannot slide past one another. •

Detailed explanation-3: -Solid In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.

Detailed explanation-4: -Expansion is due to an increase in the average distance between atoms (or molecules) in the substance. The atoms themselves do not expand-they just move further away from their neighbours. Contraction is due to an decrease in the average distance between atoms (or molecules) in the substance.

Detailed explanation-5: -Gases-particles in a gas are not held together by strong forces of attraction so they are free to move in all directions. From the descriptions, the state of matter where particles are close together but are free to move around each other is a liquid.
