2. • Explain the particle nature of matter.
Objectives:
• Compare the properties of solids, liquids and
gases in terms of arrangement and movement
of particles.
• Identify samples as matter based on its
general/common properties.
3. ELEMENTS COMPOUNDS
In Grade 7 you have learned
how to classify materials such
as mixtures, elements and
compounds.
All of these are matter.
HOMOGENOUS
MIXTURE
HETEROGENOUS
MIXTURE
5. HEAT is the energy
being transferred
between bodies
from high to low.
LIGHT is a form of
energy that is visible
to human eye.
If Heat & Light are
forms of energy, and
energy is not a form of
matter because it is not
composed of atoms or
molecules.
Therefore, Heat & Light
are not matter.
6. What is matter?
Matter is anything that occupies space and has mass.
NON-LIVING THINGS LIVING THINGS
7. Properties of Matter
MASS is the amount of matter in an object. You can measure
mass of an object by using a balance or a weighing scale. It is
the property of matter that will not change under all
conditions.
are characteristics that describe the matter.

Matter can also occupy space. The measure of the space
occupied by an object is called VOLUME.
8. All matter have mass and volume.
There are other properties of matter
such as:
hardness,
texture,
color,
flexibility,
malleability,
and electrical conductivity

about a fixed position.

12. What is matter made of?
A particle is a word
we use for a small
piece of matter.
Matter is made up of
very small particles.

The particulate theory of matter describes what matter is made of.
13. Particulate
Nature of
Matter
The particles are very small, invisible and cannot
be seen with our naked eye.
There are spaces between particles in matter. The
spaces between particles are different in solids,
liquids & gases.
The particles of matter move at different speeds in
solids, liquids and gases.
The particles are in constant and in random
motion.

14. The ancient Greek philosophers proposed ideas about what matter
was made of. Almost 2,500 years ago, Leucippus and his disciple,
Democritus believed that nature consisted of two things, “atoms and the
void that surrounds them” (Knieram, 1995-2013).
They believed that “atoms are physically, but not geometrically,
indivisible.” For Democritus, atoms are indestructible and completely full, so
there is no empty space.
Both Leucippus and Democritus had the idea that there are many
different kinds of atoms and each of them had specific shape and size and
that all atoms move randomly around in space. However they did not give an
explanation for the motion of atoms. (Knieram, 1995-2013).
15. Democritus believed that any piece of matter can be divided and
subdivided into very small particles but that this process ended at some
point when a piece is reached that could not be further divided.
He called this particle, “atomos”, a Greek word which means
indivisible particle. Democritus’ ideas about the atom were later challenged
by other Greek philosophers, most strongly by Aristotle.
16. The idea of the atom was not further explored until a little over two
centuries ago when John Dalton presented concrete evidence that all matter
is made of very small particles called atoms.
Today, we know that although atoms are very small, they are not indivisible as
Democritus thought, rather they consist of still smaller particles,

30. SUMMARY:
All matter has mass and has volume.
Particulate Nature of Matter:
The particles are very small, invisible and cannot be seen
with our naked eye.
There are spaces between particles in matter. The spaces
between particles are different in solids, liquids & gases.
The particles of matter move at different speeds in solids,
liquids and gases.
The particles are in constant and in random motion.
An atom is the smallest particle of an element but it has its
subatomic particles called neutron, electron and proton.

40. Physical Properties
Physical properties are used to
identify, describe and classify
matter.
Characteristic of a substance
that can be observed (using
your senses) without
changing the substance into
something else.
41. Changes in Matter
Change in state of matter is brought
about by absorbing or releasing an amount
of energy or heat.
PHYSICAL CHANGE
- when the composition of the substance
is not altered in the process.
44. Melting point
The temperatures at
which the solid form
of the element or
compound is at
equilibrium with the
liquid form.
Basically the range at
which the solid
changes its state into
a liquid.
The melting
point of ice is
zero degrees
Celsius.
47. 3.Evaporation
The change of a
substance from
liquid to gas.
Volatile Liquids
evaporates
easily (acetone,
perfume, benzene,
hexane)
48.
49. Boiling point
The boiling point of an
element or compound
means the temperature at
which the liquid form of
an element or compound
is at equilibrium with the
gaseous form.
The boiling point of water
is 100 degrees Celsius.
55. Changes in Matter
CHEMICAL CHANGE
- or a chemical reaction occurs when the
composition of a substance is changed into
a substance having physical and chemical
properties completely different from the
original.
- evidences of chemical change: change in
color, odor, taste or release of gas
