The document discusses the three states of matter - solids, liquids, and gases. It defines each state and provides examples. Solids have a definite shape, mass and volume. Liquids have a definite mass and volume but not a definite shape. Gases do not have a definite shape, mass or volume. The document aims to teach students to classify items as solids, liquids or gases based on these defining properties.

1. The Three
States
of Matter

2. Three States of Matter
Learning objective:
Students will be able to classify the pictures
as solids, liquids, or gases.
Student goals:
I will know what matter is.
I will know what the three states of
matter are and their properties.
I will know how to classify items as solids,
liquids, or gases.

3. What is Matter?

4. Matter is anything that takes
up space and has mass.

5. What are the States of Matter?

6. There are three states of matter:
solids, liquids, and gases.

7. What is a Solid?
A solid is the simplest state of matter.
A solid has these three main properties:
rigid, compact, incompressible
definite mass, shape, volume
Iit do not flow
A solid will always look the same and take up the
same amount of space.

8. Examples of Solids:
Colored
Pencils
Basketball
Chair

9. 1. Crystalline – most common type of solid and has well
define shape.
Ex. Diamond and graphite
2. Amorphous – are non crystalline solid
Charcoal – produced by destructive distillation of wood
Carbon black – powdery soot formed from incomplete
combustion of natural gas; used in printing inks, carbon
paper, type writer ribbons, photocopy machines.
Activated carbon – resulted from carbon black heated
between 800-1000C; used in gas mask and water filters.
Glass – used in dinner wares
Rubber – used in car tires.
Types of Solid

10. What is a Liquid?
A liquid is the ever-changing state of matter
It is mostly liquid but is also considered a fluid – a
substance that has the ability to flow.
It diffuses at a slower rate than gas
Viscosity – refers to the resistance of a liquid to flow.
A liquid has these three main properties:
• have definite volume but no definite shape
• flow and diffuse slowly
• almost incompressible, exert pressure
A liquid will always take up the same amount of space and
take the shape of its container.

11. Examples of Liquids:
Orange Juice
Cough Syrup
Salad Dressing

12. Other properties of liquid:
Surface tension- the property of the surface of the liquid that make it
resist an external force.
Ex. Needles, paper clip, razor
Wetting ability – the ability of the liquid to spread uniformly and form a
thin film over the surface
Ex. Mercury, water, petroleum
Capillary action- results from the competition between cohesive and
adhesive forces.
Ex. Absorbing capacity of cotton, paper towel, or of the parts of the trees
Vaporization - transformation of liquid into gas.
- evaporative cooling – decrease liquid temperature
- boiling – liquid is heated to its boiling point

13. What is a Gas?
A gas is the most complex and difficult to
understand state of matter
A gas has these three main properties:
• have no definite shape and volume.
• flow and diffuses easily.
• are compressible.
• exert pressure
A gas does not always weigh the same or take up the
same amount of space.
However, like a liquid, a gas will always take the shape
of its container, no matter the size or shape of that
container.

14. Examples of Gases:
Smoke
Air

15. On your worksheet, decide whether
these items are solids, liquids, or gases.
Glass
bowl
Contents inside
empty water bottle
Vinega
r
M&Ms
Steam
Milk

16. Key
Points:
Matter is anything is anything that has mass and
takes up
space.
The three states of matter are:
solids, liquids and gases.
Solids:
have a definite shape, mass and volume.
Liquids:
have a definite mass and volume, but not shape.
Gases:
do not have a definite mass, volume, or shape.
