Phases of Matter

Solid

Solids have a fixed shape and volume, with particles that are tightly packed and vibrate in fixed positions.

Solid Molecules

In solids, molecules are tightly packed and held in fixed positions by strong intermolecular forces. They vibrate in place but do not move freely.

Properties of Solids

• Fixed Shape: Solids maintain a constant shape regardless of container.
• Fixed Volume: Solids have a constant volume.
• Particle Movement: Molecules vibrate in fixed positions but do not move freely.
• Density: Generally denser than liquids and gases.
• Incompressibility: Solids are difficult to compress due to close molecular packing.
• Rigidity: Solids resist deformation due to strong intermolecular forces.
