Solid
In chemistry, a solid is one of the four fundamental states of matter. Solids have a fixed volume and shape, and the particles are packed closely together in a regular, orderly arrangement. The intermolecular forces in solids are strong, which accounts for their rigid structure.
Properties of Solids
- Definite Shape: Solids have a fixed shape that does not conform to the shape of their container.
- Definite Volume: The volume of a solid remains constant under normal conditions.
- Strong Intermolecular Forces: The particles in a solid are held together by strong intermolecular forces, resulting in a rigid structure.
- Low Compressibility: Solids are difficult to compress due to the close packing of particles.
- High Density: Solids generally have high density due to the close arrangement of particles.
Types of Solids
There are different types of solids based on the arrangement of particles:
- Crystalline Solids: These solids have a highly ordered and repeating arrangement of particles, resulting in distinct crystal lattice structures. Examples include salt, diamond, and quartz.
- Amorphous Solids: In contrast to crystalline solids, amorphous solids have a disordered arrangement of particles without a distinct crystal lattice. Examples include glass, plastic, and gels.
- Molecular Solids: These solids consist of individual molecules held together by intermolecular forces. Examples include ice and sugar.
- Atomic Solids: Atomic solids are composed of individual atoms bonded together to form a solid structure. Examples include noble gases in their solid state and metals.
Study Guide
To understand the topic of solids, it is important to cover the following key areas:
- Definition of a solid and its properties
- Understanding the different types of solids and their characteristics
- Exploring the structure and properties of crystalline and amorphous solids
- Relating the behavior of solids to their intermolecular forces
- Examining real-life examples and applications of different types of solids
Additionally, practicing problem-solving related to the properties and behavior of solids can help reinforce the understanding of this topic.

Physical Science
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
Relate temperature to the average molecular kinetic energy.
