Study Notes
States of Matter
- The three states of matter are solid, liquid, and gas.
- Solids have particles that are closely packed together in a regular arrangement.
- Liquids have particles that are close together but can move around each other.
- Gases have particles that are far apart and move randomly.
- Solids have a fixed shape and volume.
- Liquids have a fixed volume but not a fixed shape.
- Gases have neither a fixed shape nor a fixed volume.
- Solids can change to liquids through melting.
- Liquids can change to solids through freezing.
- Liquids can change to gases through evaporation.
- Gases can change to liquids through condensation.
- Solids cannot be easily compressed, while liquids are only slightly compressible, and gases can be easily compressed.
