When a substance absorbs heat energy from the surrounding
environment, its temperature increases / decreases.
The gain of heat energy causes the __ __ __ __ __ __ __ __ within the
substance to move more / less which in turn results in there being
more / less space between them.
This causes the substance as a whole to expand / contract, and it’s
volume increases / decreases.
An increase in temperature of a gas stored in a container will result in
a build up of __ __ __ __ __ __ __ __.
This is due to the increased __ __ __ __ __ __ of collisions between the
particles and the container. If the build up is great enough, there is a
risk that the container may __ __ __ __ __ __ __.

Every substance in the universe is made up of __ __ __ __ __ __. The amount of
__ __ __ __ __ __ in an object is called __ __ __ __ . V __ __ __ __ __ is a measure of
__ __ __ __ __ occupied by matter.
The particle model is used by scientists to understand the physical properties of
solid liquids and gases. The particle model makes three assumptions:
1.
All matter is made up of very small __ __ __ __ __ __ __ __ __
2.
These particles are constantly __ __ __ __ __ __ and/or vibrating
3.
There are __ __ __ __ __ __ of attraction between the particles

Write a description of the motion and spacing of the particles as they change state.
1.
Sublimation occurs
when the particles of a
solid absorb enough
energy to completely
overcome the force of
attraction between
them. As the particles
move much faster and
have no attractive
forces they become
very spread out.
2.
Melting occurs when
the particles in a solid
gain enough energy to
overcome the bonding
forces holding them
firmly in place. The
particles still stay close
to their neighbouring
particles, but are able
to move more freely.
3.
Vaporisation occurs
when the particles in a
liquid gain enough
energy to overcome
the bonding forces
holding them loosely in
place in the liquid and
they become free, fast
moving, individual
particles in a gas.
4.
Solidification occurs
when the particles in a
liquid lose energy and
stop moving about.
They settle into a
stable close
arrangement, forming
a solid.
5.
Condensation occurs
when the particles in a
gas lose energy, stop
moving about so fast
and form a liquid with
bonding forces holding
them loosely together.
