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.
