Solid

A solid is one of the three main states of matter, along with liquid and gas. Solids have a definite shape and volume, and their particles are closely packed together in a regular arrangement. This close packing of particles gives solids their strong structure and resistance to changes in shape.

Characteristics of Solids:

• Definite shape: Solids maintain a fixed shape and do not flow to take the shape of their container.
• Definite volume: The volume of a solid remains constant, as the particles are closely packed together.
• Strong structure: The particles in a solid are held together by strong forces, giving solids their rigidity.
• Low compressibility: Solids are difficult to compress due to the close arrangement of particles.
• High density: Solids are typically denser than liquids and gases due to the close packing of particles.

Examples of Solids:

Common examples of solids include:

1. Wood
2. Metal
3. Plastic
4. Rock
5. Ice
