The solid state is one of the four fundamental states of matter. In a solid, the molecules are bound together by very strong intermolecular forces, and the molecules cannot move freely. Solids have a definite shape and volume, and cannot be compressed. Most solids are hard, although some, such as wax, are soft.
Solids are divided into three categories: crystalline, amorphous, and polymorphous. Crystalline solids have an ordered, geometric structure, while amorphous solids do not have an ordered structure. Polymorphous solids are solids that can exist in more than one crystalline form.
Most solids form when they are cooled slowly from a liquid or gas. Rapid cooling often prevents the molecules from arranging themselves correctly, resulting in an amorphous solid. Pressure can also influence the formation of a solid, and some solids, such as diamond, only form at high pressures.
Crystalline solids are formed when molecules are arranged in an ordered, repeating pattern. The structure of crystals is determined by the shape of their molecules and the way they are arranged. Examples of crystal structures include body-centered cube (BCC) and hexagonal closed cube (HCP).
Amorphous solids do not have an ordered structure. They usually form when a liquid or gas is cooled rapidly, which prevents the molecules from ordering themselves correctly. Amorphous solids have physical properties that are intermediate between crystalline solids and liquids.
Polymorphs are solids that can exist in more than one crystalline form. Polymorphism is the result of the interaction between the structure of molecules and environmental conditions, such as temperature and pressure. Examples of polymorphism include water (H2O), carbon (C), and silicon (Si).

What is solid state?
The solid state is one of the four fundamental states of matter and is characterized by molecules being in constant contact with each other. Because of this interaction, solids have a fixed shape and volume. Solids can also be rigid, meaning they do not change shape when an external force is applied to them.
What is solid state and examples?
The solid state is one of the four states of aggregation of matter, in which matter is firmly bound and rigid. Solids have a fixed shape and volume. Most naturally occurring solids are chemical compounds, such as minerals. Some elements, such as carbon (diamond, graphite) or silicon (silica), exist in a solid state in nature. Water, although a compound, can also exist in a solid state (ice).
What is solid state for elementary school children?
The solid state is a state of matter in which the molecules are tightly bound together and cannot move freely. Solids have a definite shape and size, and cannot expand or contract. Solids do not have a definite shape, but they do have a definite size. Solids cannot expand or contract.
What is the liquid state?
The liquid state is a state of matter in which the particles (atoms or molecules) have a certain amount of energy and are in continuous motion, but they do not separate as in the gaseous state. In other words, in the liquid state the particles are far enough apart to move freely, but close enough together so that they do not separate.
