If you look around, you may see people and a variety of things, such as books,
desks, chairs, vehicles, and buildings. You may also see plants, animals, mountains,
clouds, rivers and many other things.
Everything found in the environment is matter. Each has certain properties that
make it different from others.
Different forms of matter are seen everywhere. They can be in solid, liquid and
gaseous forms. Many of the things that you use every day are materials in solid,
liquid and gas.
Matter can be classified according to its characteristics and properties. Knowing
the properties of matter can help you determine its uses and how each form can be
changed.
After going through this learning material, you will know more about matter and
be able to attain the following objectives:
Learning Competency:
Explain the properties of solids, liquids, and gases based on the particle nature
of matter (S8MT-IIIa-b-8)
Subtasks:
1. Explain the particle nature of matter.
2. Use simple diagram to describe the arrangement of particles of solids, liquids and
gases.
3. Compare the properties of solids, liquids and gases in terms of arrangement and
movement of particles

Let’s check how much you know about matter by doing the next activity.
Activity 2: Identifying Matter
Direction: Identify whether the following materials are matter or not. Put a check
mark on the appropriate column.

What is matter?
Matter occupies space and has mass. It can be a solid, liquid or gas. All
nonliving things, such as chairs, tables, stones and water are matter. All living
things, such as plants and animals, are also matter.
How can you identify matter? Matter can be identified by knowing its different
characteristics and properties.
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. Matter can also occupy space. The measure of the space
occupied by an object is called volume. All matter has mass and volume.
While the general properties of matter are evident in all forms of matter, there
are also other properties that are manifested only in certain materials. These are
specific properties of matter, some of which are elasticity, flexibility, malleability,
ductility, brittleness, conductivity and porosity.
The particulate theory of matter describes what matter is made of. Scientists
believe that matter is made up of very small particles. A particle is a word we use for
a small piece of matter. We can see small pieces of salt. However, scientists believe
that slat is made up of even smaller particles that we cannot see.

The idea of matter being made of atoms has been recognized a long time ago.
Some of the early ideas about the composition of matter according to the Greek
philosophers and scientists will be discussed below.
According to Thales of Miletus, all things came from water, and the Earth itself
float on water. A century after Thales’ death, Leucippus, a Greek philosopher,
conceived the idea of indivisible units called atoms (meaning “uncut”). This idea was
developed in the late fourth and early fifth centuries B.C. by Democritus, a student
of Leucippus to whom Aristotle attributed the atomic theory. Democritus believed
that matter consisted of tiny particles called atomos and that the infinite variety of
observable things could be explained by the combinations of different sizes and
shapes of these particles.
Empedocles, a contemporary of Democritus, proposed that matter is made up
of four elements – fie, earth, air and water.
Aristotle rejected the idea of the atomism of matter. He believed that there is no
limit to subdividing matter. Dividing matter in small bits can go on infinitely with
each piece getting smaller and smaller.
The idea of an atom began to be of operational significance when John Dalton
showed that this could explain the existing laws of chemical combination. He chose
the word atom to express the idea of indivisibility. He pictured an atom as a tiny
indestructible sphere with mass.
The Atomic Theory of John Dalton presented a concrete evidence that all matter
is made of very small particles called atoms. An atom is the smallest particle that
has all the properties of the element. Although we know that atom is very small,
today, we know that they are not indivisible as Democritus thought. An atom is still
consisting of even smaller particles.

Atoms are very small that it can’t be seen by our naked eyes or even a high-
powered light microscope that is used in laboratories. The size of an atom is
measured in angstroms. One angstrom is a unit of length equal to one ten millionth
of a millimeter.

Solid
In solids, particles are close to each other, are compact. A solid has a definite
shape and volume. Particles are arranged in a regular or fixed pattern. Particles
cannot move freely but constantly vibrate in their fixed positions. Solids cannot flow
and can’t be compressed since its particles are compact. Rocks, books, pens, erasers
and blackboards are examples of solids. The particles of solids are held together by
a strong force. One common characteristic of both solid and liquid is that the
particles are in contact with their neighbors, that is with other particles. Thus they
are incompressible and this commonality between solids and liquids distinguishes
them from gases.

Liquid
The molecules of liquids are arranged and positioned far from each other. Since
the particle are closer to one another, the attraction between particles is stronger
than those in gases. Their molecules move more freely or can flow easily than those
of solids and it can be poured into another container without changing their volume;
hence, they have no definite shape but have definite volume. This happens because
there are attractions between particles of liquid which hold them together although
not in fix positions. A liquid takes the shape of its container. Particles are not
arranged in fixed regular pattern. Particles constantly move over short distances and
slide across each other. Water, juice, milk, and carbonated drinks are examples of
liquid.

0It's%20Just%20a%20Phase_files/phase2.gif
Gas
The molecule of gases moves freely in all directions and are arranged farthest
from one another. Gases have no definite shape and volume. They take the shape
and volume of the container they are in. The particles of gases move at random
directions very quickly and travel in straight-line paths. In the process they collide
with one another and with the walls of the container. They change directions only
when they rebound from the collisions. The distance between the particles are large
compared to the size of the particles. The attraction between particles are negligible
because of the large distance between them. This explains why gas spreads. Its
particles fill all the available space in the container.
Gases takes the shape of the container because the particles are able to move
freely to all parts of the container. They move freely because they are far apart and
there is negligible attraction between them. This model also explains the
compressibility of gases. The distance between particles are large and so there are
rooms for particles to move closer to each other.
Gases can be felt and smelled, but cannot be seen nor tasted. Unlike liquids
and solids, they can be compressed and can even occupy small spaces. Examples of
gases are carbon dioxide, hydrogen, oxygen and nitrogen.
Both liquid and gases flow freely; hence, they are called fluids.

At this point you are now ready for your last activity. Remember the things
that you learned in this lesson. Good luck!!!
Water Power
What do you, the trees, and a dog have in common? Give up? You all need water.
All living things must have water to survive, whether they get it from a water fountain,
a rain cloud, or a little bottle attached to the side of a dog cage.
Without water, your body would stop working properly. Water makes up more
than half of your body weight, and a person can't survive for more than a few days
without it. Why? Your body has lots of important jobs and it needs water to do many
of them. For instance, your blood, which contains a lot of water, carries oxygen to all
the cells of your body. Without oxygen, those tiny cells would die and your body
would stop working.
Water is the most important liquid that every living thing needs. Water is also
one of the few substances that can exist as solid, liquid and gas.
For your last activity, here is what you’re going to do.
What to do: Your task is to draw the three states of water showing the arrangement
particles in each state.
