As seen here in the figure, the particles of solids are tightly packed in a regular pattern. Particles of liquid are less tightly packed as compared to solids and in gases, the particles are loosely packed with no regular pattern.

Particles of solids are tightly packed as compared to that of gases.
Solid Particles:
- In a solid, the particles are closely packed together and are held in a fixed position.
- The particles vibrate in their positions but do not move from one place to another.
- The forces of attraction between the particles are strong, keeping them closely packed together.
- Due to the strong forces of attraction, solids have a definite shape and volume.
- Examples of solids include wood, metal, and stone.
Gas Particles:
- In a gas, the particles are far apart and move freely in all directions.
- The particles have a lot of space between them and are not held in a fixed position.
- The forces of attraction between gas particles are weak, allowing them to move and spread out.
- Due to the weak forces of attraction, gases do not have a definite shape or volume. They take the shape and volume of their container.
- Examples of gases include air, oxygen, and carbon dioxide.
Comparison:
1. Particle arrangement:
- Solid particles are tightly packed and arranged in a regular pattern, forming a rigid structure.
- Gas particles are far apart and arranged randomly, with no specific pattern.
2. Particle movement:
- Solid particles vibrate in their positions but do not move from one place to another.
- Gas particles move freely and rapidly in all directions.
3. Forces of attraction:
- Solid particles have strong forces of attraction between them, keeping them closely packed together.
- Gas particles have weak forces of attraction between them, allowing them to move and spread out.
4. Shape and volume:
- Solids have a definite shape and volume due to the closely packed arrangement of particles.
- Gases do not have a definite shape or volume. They take the shape and volume of their container.
Conclusion:
The particles of solids are tightly packed together due to strong forces of attraction, while the particles of gases are far apart and move freely. This fundamental difference in particle arrangement and movement is why solids have a definite shape and volume, while gases do not.
