Study Notes
States of Matter
- There are four fundamental states of matter: solid, liquid, gas, and plasma.
Characteristics of Solids
- In a solid, molecules are closely packed and have a fixed position in space.
- The molecules in a solid vibrate in place, but do not change their position.
Solid vs Liquid
- The key difference between a solid and a liquid is the arrangement of molecules.
- In a solid, molecules are closely packed and have a fixed shape, while in a liquid, molecules are close together but are free to move past each other.
Types of Solids
- There are two types of solids based on atomic arrangement: crystalline and amorphous solids.
- Crystalline solids have a regular, three-dimensional arrangement of atoms, while amorphous solids have a random arrangement of atoms.
Physics of Solids
- The branch of physics that deals with solids is called solid-state physics.
- Solid-state physics studies the behavior of solids and their properties, such as mechanical, thermal, electrical, and magnetic properties.
