Matter is anything that occupies space and has mass. It exists in various states depending on the behavior and arrangement of its atoms and molecules. The three main states of matter are solids, liquids, and gases. Solids have a fixed shape and volume, with atoms closely bonded in a rigid structure. Liquids have a fixed volume but can change shape, as atoms are loosely bonded and free to move around one another. Gases have no fixed shape or volume, as atoms are very far apart and move freely in all directions. The states can change from one to another when sufficient heat is added or removed without altering the chemical makeup of the substance.

1. Matter
Matter is anything that occupies space and
has mass. All physical objects are
composed of matter, and an easily
observed property of matter is its state or
phase.

2. Matter
- anything that has mass and volume
Mass
Mass is how much
stuff something is
made of
Volume is how
much space an
object takes up.
Volume

3. States of matter can be more than just your average solids, liquids
and gases!
When water turns into snow, is it still water? The answer is yes!
Our world is filled with solids, liquids, gases and even other matter
that can go from one state of matter to another without changing
its chemical substance. In this lesson, students explore these
different states of matter and their interactions.
States of Matter

4. “state of matter” is a
way to describe the
behaviour of atoms and
molecules in a
substance.
States of Matter

5. States of Matter
Relatively rigid, definite volume and shape.
In a solid, the atoms and molecules are closely
bonded that they vibrate in place but don't
move around.
Solid

6. Properties of Solid
Solid has a fixed shape and a fixed volume.
Solid cannot be compressed.
Solids have a high density.
Force of attraction between the particles in a solid is
very strong.
The space between the particles of solids is negligible.

7. States of Matter
Definite volume but able to change shape by
flowing. In a liquid, the atoms and molecules
are loosely bonded. They move around but
stay close together
Liquid

8. Propeties of Liquid
Liquid has a fixed volume but no fixed shape.
Liquids can be slightly compressed. large pressure is
required to compress them.
Liquids have lesser densities than solids.
Intermolecular forces of attraction is weaker than solids.
They have considerable space between the particles.

9. States of Matter
No definite volume or shape. The atoms and
molecules move freely and spread apart from
one another.
Gas

10. Properties of Gas
Compressibility- Particles of gas have huge intermolecular
spaces in the midst of them.
Expansibility- When pressure is exerted on gas, it contracts.
Diffusibility- The molecules of the gas are in perpetual motion,
at a very high velocity
Low Density. ...
Exertion of Pressure.

materials.
Materials : Directions: Make a pamphlet using a
colored paper. Fold it and make 3
divisions. For the front page create the
title of your pamphlet " States of Matter".
for the following pages print/ draw the
three states of matter and its properties
and samples of each state.
