What is matter made of? How does the particle model of matter explain some observed properties and changes in matter? Explain the properties of solids, liquids, and gases based on the particle nature of matter.
Understand the Problem
The question is asking about the composition of matter and how the particle model of matter explains its properties and changes. Additionally, it seeks an explanation of the properties of solids, liquids, and gases based on this model.
Answer
Matter is made of atoms and molecules. Solids have closely packed particles, liquids have loosely packed particles, and gases have widely separated particles.
Matter is made of tiny particles called atoms and molecules. The particle model of matter explains properties like shape, volume, and compressibility by describing the behavior and arrangement of these particles. Solids have closely packed particles, liquids have loosely packed particles, and gases have widely separated particles that move freely.

Solids have closely packed particles, liquids have loosely packed particles, and gases have widely separated particles that move freely.
More Information
The particle model provides a theoretical framework for understanding why different states of matter have distinct properties. For example, the rigidity of solids is due to the strong forces holding particles in fixed positions.
Tips
A common mistake is failing to account for the space between particles in different states, affecting properties like compressibility.
