Class 9 Chemistry Matter In Our Surroundings Solid state

Solid state

  • They have definite shape due to strong Intermolecular forces of attraction.
  • They have distinct boundaries.
  • They have a fixed volume.
  • They cannot flow.
  • They have negligible compressibility due to negligible distance between the neighbouring molecules.
  • They possess a tendency to uphold their shape when exposed to external force.
  • They break under force but it is difficult to change their shape so they are rigid.
  • They have high density and do not diffuse at all.
