General Properties of Solids

The Solid State: In solids, the intermolecular force of attraction being large, the particles of matter come very close and these are very strongly held together. The intermolecular space becomes small. The molecules, therefore, are not free to move from one place to another within the solid.

General Properties of Solids:

  • Shape and volume.
  • Density
  • Melting Point and boiling Point.
  • Compressibility.
  • Flow
  • Exansion or Contraction.
  • Sublimation
  • Diffusion.
  • Sublimation:  The process, by which solid changes directly into its vapours without passing through the liquid state, and the vapour changes directly back into the solid in its original form, is known as ‘sublimation’. On cooling, the vapours change directly back into the solids without going through the liquid state. The solid obtained as a result of sublimation is called the ‘sublimate.’

  • For example: iodine, ammonium chloride, camphor, naphthalene, dry ice etc. Take some ammonium chloride in a porcelain dish and cover it with an inverted conical funnel as shown.
  • A test tube is inverted on the stem of the funnel. The basin is now heated on a sand bath. Ammonium chloride sublimes off as vapour and gets deposited on the cooler parts of the test tube.
  • This method is usually employed to separate a sublimable solid from an unsublimable one.
