usually exist as at r.t.p (room temperature and
pressure)? _____________________
• Can ionic compound exist as other states?

Lesson Objectives
At the end of this lesson, you should be able to:

 Describe the solid, liquid and
gaseous states of matter
WHAT IS A MATTER?
(a)Matter is anything that has ______ and
___________________________.

(b)All matter is
_______________________________(atoms,
molecules or ions).
Use of the general term 'particle' means the precise nature of
the particles does not have to be specified.

(c)Matters can exist in 3 states: ________,
__________________and ______________.
• These three forms of matter are called the
______________________________.

• As shown here, ___________ (liquid) can exist
as ice (____________) or water vapour (_____).
KINETIC THEORY OF MATTER
The kinetic particle theory is a model
used to explain the _____________of
matter.
Kinetic Theory of Matter states that:

(i) All matter is made up of _______
particles and they exist as atoms,
molecules or ions. (The particles are
attracted to each other by
attractive forces)
KINETIC THEORY OF MATTER
(ii) The particles are always in
_______________________________ and
hence possess ___________ energy.
**(The _____________ energy of a particle
increases with _______________and
__________________, the higher the
temperature and pressure, the
_____________the particles move. At
fixed temperature, _____________
particles move ____________________
than heavier particles.)
KINETIC THEORY OF MATTER
The particles in a substance are of the same
type, in solid, liquid or gaseous state. The
differ only in
•   their _____________________
•   how __________________the particles are
held together and
•   the amount of
_____________________energies that they
possess.

_______________ can be used to explain how
solids, liquids and gases differ in
