Study Notes
Forms of Matter
- Plasma is the least common form of visible matter in the universe, representing a unique state where gases are ionized.
- Bose–Einstein condensates and neutron-degenerate matter are primarily observable under specific conditions, not typically encountered in daily life.
Properties of Liquids and Gases
- Liquids maintain a fixed volume but adapt to the shape of their container, showcasing fluidity.
- Gases have very weak intermolecular bonds, allowing molecules to move freely and expand to fill available space.
Characteristics of Solids
- Solids maintain a defined shape under normal conditions, but they can deform without external force through elastic or plastic deformation.
- Iron possesses a face-centered cubic structure at temperatures below 912 °C, which affects its mechanical properties.
- Ice exhibits ten known crystal structures or solid phases, indicating complexity beyond a simple uniform structure.
Unique States of Matter
- Quark–gluon plasmas are observable states of matter that exist under extreme conditions, such as those found in high-energy particle collisions.
- Non-crystalline solids like glasses exhibit long-range order, contrasting with traditional crystalline structures that have a highly ordered arrangement.
