Nature of gases, liquids and solids
Gases are made up of
particles which move with rapid random motion. The size of the particles and
any intermolecular forces can be ignored unless the particles are close
together at high pressure or at low temperature.
In liquids, the particles
are in a state of order intermediate between that of a gas and that of a solid.
At any instant in time the arrangement of particles resembles a somewhat
disordered solid. Over a period of time the disordered regions allow all the
particles in the liquid to move through the liquid. The particles are held
together by forces similar to those in a solid.
In solids, the particles
remain in fixed positions, about which they can vibrate. The forces which hold
the particles together can be ionic attractions, covalent bonds, metallic
bonds, hydrogen bonds, dipole-dipole forces or van der Waals' forces. Heat
energy is required to change a solid into a liquid at its melting point. The
energy is used to loosen the forces which hold the particles together. This
heat energy is called the enthalpy of fusion.
More energy is needed to
change phase from a liquid into a gas than to change from a solid into a
liquid. The energy is used to overcome the forces which hold the particles
together so that the particles can be completely separated. This heat energy is
called the enthalpy of vaporisation. |
