1. Solid:
- Definite shape and volume
- Fixed molecular positions/strong intermolecular forces
- High density
- Incompressibility
- Low fluidity/rigidity
- Example: Ice
2. Liquid:
- Indefinite shape (assumes the shape of its container) but definite volume
- Loosely packed molecules with weak intermolecular forces
- Relatively incompressible except under extreme pressure
- Less dense than solids but denser than gases
- Flow readily or exhibit fluidity
- Example: Water
3. Gas:
- No definite shape or volume (expand to fill their container)
- Highly dispersed molecules with almost negligible intermolecular forces
- Highly compressible
- Lowest density among the three states of matter
- Flow easily
- Example: Air
Please note that there are additional states of matter beyond these three (such as plasma and Bose-Einstein condensate), but they occur under specific conditions not commonly encountered in everyday life.
