The particle model
7 of 23 © Boardworks Ltd 2007
The difference between solids, liquids and gases can be explained
by the particle model.
 All substances are made up of
particles.
 The particles are attracted to
each other. Some particles are
attracted strongly to each other
and others weakly.
 The particles move around.
They are described as having
kinetic energy.
 The kinetic energy of the
particles increases with
temperature.

Solids, liquids and gases
10 of 23 © Boardworks Ltd 2007
 has a high density as the particles
are very close together.
 cannot be compressed as there is
very little empty space between
particles.
 has a fixed shape as the particles
are held together tightly by strong
intermolecular forces of attraction.
 cannot diffuse as the particles are
not able to move freely, vibrate
about a fixed point only.
 does not exert any pressure as the
particles cannot move around to
collide with the walls of the
container.
What are the properties of solids?
A solid:
11 of 23 © Boardworks Ltd 2007
 has a fairly high density as the particles are close
together enough to touch and slide past one another.
 cannot be compressed as there is very little empty
space between particles.
 takes up the shape of its container
as the particles can move to an
extent– are not in a fixed position.
 can exert some pressure as the
particles are able to move by
sliding past one another and collide
with the sides of the container.
What are the properties of liquids?
A liquid:
12 of 23 © Boardworks Ltd 2007
 has a low density as the particles are far apart
 can be compressed as there is space between
particles
 has no fixed shape as the particles move
about rapidly in all directions
 can diffuse as the particles can
move freely in all directions.
 can exert a lot of pressure as the
particles are able to move in all
directions and collide with the sides
of the container.
What are the properties of gases
A gas:

Diffusion
15 of 23 © Boardworks Ltd 2007
 gas – The state of matter in which particles can freely move, and
in which substances have no fixed volume or shape.
 liquid – The state of matter in which particles are close together
but free to move, and in which substances have a fixed volume
and assume the shape of their container.
 matter – The stuff that everything is made of.
 particle – The smallest unit of matter.
 pressure – The force produced when particles move against a
surface.
 solid – The state of matter in which particles are close together
and cannot move, and in which substances have a fixed shape
and volume.
