Solid
A solid is one of the three main states of matter, along with liquid and gas. Solids have a definite shape and volume. The particles in a solid are closely packed together and vibrate in place. They have a strong attraction to each other, which keeps them in a fixed position.
Properties of Solids:
- Definite shape: Solids maintain their shape and do not flow like liquids.
- Definite volume: Solids have a fixed volume and do not change their volume easily.
- Strong intermolecular forces: The particles in a solid are held together by strong forces, which make them difficult to separate.
- Low compressibility: Solids are difficult to compress because the particles are already close together.
- High density: Solids are usually denser than liquids and gases because of the close packing of particles.
Examples of Solids:
Common examples of solids include ice, wood, metal, plastic, and rock.
Study Guide:
Here are some questions to help you study the topic of solids:
- What are the three main states of matter?
- What are the properties of solids?
- How do the particles in a solid behave?
- Give examples of solids in everyday life.
- What is the difference between the shape and volume of a solid?
Understanding the properties and behavior of solids is essential for understanding the world around us and the behavior of different materials.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
