Forces of Attraction in Solids
- In solids, the molecules are closely packed together and have a fixed position.
- The forces of attraction between the molecules in solids are the strongest among the three states of matter.
- This strong attraction holds the molecules in a fixed position, giving solids a definite shape and volume.

Forces of Attraction in Liquids
- In liquids, the molecules are still close together but are able to move around each other.
- The forces of attraction between the molecules in liquids are weaker compared to solids but stronger than gases.
- This moderate attraction allows liquids to take the shape of their container but maintain a constant volume.

Forces of Attraction in Gases
- In gases, the molecules are far apart and move freely.
- The forces of attraction between the molecules in gases are the weakest among the three states of matter.
- This weak attraction allows gases to expand to fill their container and have neither a definite shape nor volume.

Conclusion
- Therefore, the forces of attraction between molecules are the strongest in solids, making them have a definite shape and volume.
- Liquids have moderate forces of attraction, allowing them to take the shape of their container but maintain a constant volume.
- Gases have the weakest forces of attraction, allowing them to expand to fill their container and have neither a definite shape nor volume.
