Solids Liquids Gases
Solids have a fixed shape and a fixed volume. Liquids have a fixed volume, but no fixed shape. Gases have neither a fixed volume nor a fixed shape.
Solids cannot be compressed. Liquids can be compressed. Large pressure is required to compress them. Gases can be compressed easily.
Solids have high density. Liquids have lesser density than solids. Gases have the least density among the three.
The force of attraction between the particles is very strong. The intermolecular force of attraction is weaker than solids The intermolecular force of attraction is weakest
The space between the particles of solids is negligible. They have considerable space between the particles. The space between gas particles is large.
