• Fixed shape,volume
• High Density
• Hard-require large force to change its shape
• Incompresible

2.Liquid

• Fixed volume, no fixed shape
• High Density
• Incompressible

3.Gas

• No fixed shape, volume
• Low Density
• Incompressible

Arrangement of particles

1. Solid

• High Density- Closely packed,regular pattern, ocupying minimum space.
  
• Fixed volume,shape- vibrate about fixed position only, strong intermolecular bonds

2.liquid

• High Densiy- randomly arranged,particles slightly further apart compared to solid
• Fixed volume, no fixed shape - Free to move about but confined within the vessel, strong atractive force between particles

3.Gas

• Low Density- Particles randomly arranged, occupy any available space
• No Fixed volume,shape- Particles have little attraction force, and move randomly at high speed.
