Study Notes
States of Matter
- The main difference between a solid and a liquid is the arrangement and movement of their particles.
Solids
- Particles in a solid are closely packed and have a fixed position, with little movement, resulting in a rigid structure.
- Solids have a fixed shape because their particles maintain their position and do not change their arrangement.
Liquids
- When a liquid is heated, its particles gain energy and start moving more rapidly, increasing the distance between them.
- A characteristic of particles in a liquid is that they are close together but are free to move past one another, allowing the liquid to change shape.
Understand the differences between solids and liquids, including the behavior of particles and changes that occur when heated. Learn about the characteristics of particles in each state and how they affect their shape.
