The document discusses the nature of matter, defining it as anything that occupies space and has mass, and categorizes it into solids, liquids, gases, and plasma. It describes the properties and states of matter, including characteristics such as mass, volume, weight, and density. Additionally, it highlights various changes materials undergo due to temperature, including melting, freezing, evaporation, condensation, and sublimation.

2. MATTER?

A – What A is the invisible mixture of gas? Air
T – What T is an instrument use to measure temperature? Thermometer
T – What T is the part of the mouth use to taste food? Tongue
E – What E is the organ responsible for our sense of sight?
R – What R is the part of a plant that absorbs water from the soil?
Eyes
Roots

3. OBJECTIVES
•IDENTIFY THE STATES AND CHARACTERISTICS OF MATTER
•CLASSIFY OBJECTS AS SOLID, LIQUID, AND GAS
•DESCRIBE CHANGES IN MATERIALS ON THE EFFECT OF TEMPERATURE

4. Man Air Thermometer Tongue
Eyes Roots
Examples of Matter
Give your own Examples of Matter

5. MATTER
•IT IS ANYTHING THAT OCCUPIES SPACE AND HAS MASS
•IT EXISTS EVERYWHERE
•ALL LIVING AND NON-LIVING THINGS ARE MATTER WHETHER YOU
SEE THEM OR NOT

6. STATES OF MATTER •SOLID
•LIQUID
•GAS
•PLASMA

7. Matter is made up of molecules which
are arranged according to its state. It
has properties like mass, weight,
volume, and density.

8. MASS •Refers to the amount of matter an object contains
VOLUME
•The pull of gravity on an objectWEIGHT
•The space that matter occupies. It has length, width, and
thickness
DENSITY •Is a measure of mass per unit volume
- An object which floats on water has less density than water and
an object that sinks in water has more density than water

9. PARTICLES OF SOLID
Tightly packed together
Vibrate against one another
DO NOT MOVE from one
place to another

10. Definite Shape Definite Volume
SOLID
Takes up space
Give Examples

11. PROPERTIES OF SOLID
HARDINESS Ability of solid matter to resist
scratches or cuts
MALLEABILITY
Ability of solid matter to be
hammered, molded or
pressed into various shapes
and sizes without breaking

12. PROPERTIES OF SOLID
ELASTICITY Ability of solid materials to be
stretched when pressure is applied
BRITTLENESS Tendency of materials to be
easily broken into pieces
DUCTILITY Ability to be drawn
into fine wires

13. PROPERTIES OF SOLID
FLEXIBILITY Ability of solid materials to bend
without breaking like rubber.
POROSITY Ability of solid objects to absorb
liquid like sponge, cotton, and
foam

14. PARTICLES OF LIQUID
Close Together
Vibrate past one another
LITTLE MOVEMENT

15. No shape of their
own
Definite
Volume
LIQUID
Takes up
space
Take the shapes
of the container
Give Examples

16. PARTICLES OF GAS
Not Close Together
Very Spread Out
VIBRATE FREELY Past Each
Other

17. No shape of their
own
No Definite
Volume
GAS
Takes up
space
Take the shapes
of the container

18. GIVE EXAMPLES OF GASES
•OXYGEN •HELIUM •CARBON DIOXIDE

19. PARTICLES OF PLASMA
Not Close Together
Very Spread Out
CHARGE

20. No shape of their
own
No Definite
Volume
PLASMA
Less dense
Plasmas are made up of atoms in which some or all of the electrons have been stripped
away and positively charged nuclei, called ions, roam freely.
Blood plasma, by the way, is something completely different. It is the liquid portion of
blood. It is 92 percent water and constitutes 55 percent of blood volume
Being made of charged particles, plasmas can do things gases cannot, like conduct
electricity. And since moving charges make magnetic fields, plasmas also can have
them.

21. PLASMA EXAMPLES

22. CHANGES THAT MATERIALS UNDERGO
•SOLID to LIQUID
•LIQUID to SOLID
•LIQUID to GAS
•GAS to LIQUID
•SOLID to GAS
KEY FEATURE
TEMPERATURE
is how HOT or
COLD matter is

23. SOLID TO LIQUID - MELTING
Happens when the Temperature is HIGH
Examples:
Ice turned into water
Butter melted on a hot frying pan
Give your own Examples

24. LIQUID TO SOLID FREEZING
Happens when the Temperature is LESS
Examples:
Water turned into Ice
Candle making (melted wax become candle)
Give your own Examples
The temperature at which liquid changes into solid is
called Freezing Point at 0’C

25. LIQUID TO GAS EVAPORATION
Happens when the Temperature is HIGH
When water is heated inside a kettle you can see
the hot gas coming out from the kettle
What do we call that substance coming out from the kettle?
STEAM OR WATER VAPOR

26. GAS TO LIQUID CONDENSATION
Happens when the Temperature is LOW
Evaporated water vapor condenses and form clouds

27. SOLID TO GAS SUBLIMATION
This process happens with the Help of AIR and HEAT
Changing of matter from solid to gas
WITHOUT PASSING THROUGH THE LIQUID STATE

28. QUICK REVIEW Identify the changes involved in each situation
