Solid
Definition
A solid is one of the four fundamental states of matter, characterized by structural rigidity and resistance to changes in shape or volume. In a solid, the particles are closely packed together in a regular arrangement.
Properties of Solids
- Definite Shape: Solids have a definite shape and maintain their shape unless acted upon by an external force.
- Definite Volume: Solids also have a definite volume and do not conform to the shape of their container.
- High Density: The particles in a solid are tightly packed, leading to high density.
- Low Compressibility: Solids are difficult to compress due to the close arrangement of particles.
- Strong Intermolecular Forces: The particles in a solid are held together by strong intermolecular forces, contributing to the rigidity of the solid.
Examples of Solids
Common examples of solids include ice, wood, metal, and rock.
Crystal Structure
Many solids exhibit a crystalline structure, where the particles are arranged in a specific repeating pattern. This regular arrangement contributes to the characteristic properties of solids.
