◼SWBAT classify particle

diagrams in terms of phase and
type of matter.

OBJECTIVE

All matter is made up of particles.

◼Balloons. Solid. Liquid. Gas.

PARTICLES

The particles of one substance
are the same. The particles of
different substances are made
of different particles.

Gold particles are all the same
and are different from silver
particles

The Particle Theory

•Particles are always moving
•Regardless of whether or not a substance
appears to be still, the particles that make it up
are moving
•In theory, when this movement stops, a
substance has reached its lowest possible
temperature (absolute zero…-273oC)

The Particle Theory

Longer arrows mean a higher speed.

Liquid Gas

The Particle Theory

•The more energy particles have, the faster
they move and the higher their temperature
•This movement is called heat or heat energy
•Temperature is a measurement of the speed
of the particles. Higher temperature = more
speed

Energy Increase

Longer arrows represent a
higher speed.

If energy is added or taken away, the
substance can change its state.

Energy Increase

◼Classify by:

▪_______ of matter (solid, liquid, gas)
▪______ of matter (element, compound, mixture)

Multiple Choice

Which statement correctly describes a sample of liquid confined in a sealed container?

• It always has a definite volume, and it takes the shape of the container.

• It takes the shape and the volume of any container in which it is confined.

• It has a crystalline structure.

• It consists of particles arranged in a regular geometric pattern.

Classification of Matter

All matter in the universe can be classified into
two basic categories
1. Mixtures
2. Pure Substances
A substance must be one OR the other.

Mixtures

•Homogeneous
(Solutions)

•Heterogeneous
(Mechanical Mixtures)

For the next slides, use the classification of matter organizer to write the notes.

Only write what is underlined

Homogeneous Mixtures

•Homogeneous mixtures
have identical properties
throughout the object

• All aqueous (aq) mixtures are

homogeneous
•They have one phase – look
like one thing
•Examples include saltwater,
tap water and sugar/milk
mixtures

• Heterogeneous mixtures have different

properties at different locations throughout
the object

• They have two or more phases – looks like at

least two different things

• Examples include concrete, pizza, some salad

dressing, soup, etc.

Heterogeneous Mixtures

•Elements
•Compounds

Pure Substance

•Matter that consists of one substance on
its own
•Pure substances can be elements or
compounds and have one phase
•Examples include carbon dioxide, gold,
pure water (H2O)

Pure Substance

Water Carbon dioxide Gold

•When only 1 substance makes up
an object, it is a pure substance
•Elements are the simplest pure
substance
•They cannot be chemically
altered into smaller substances
•The smallest part of an element
that still possesses the
properties of the element is an
atom

Elements

Au Au
Au Au

•Each element can be found on the periodic table
•Each element has a chemical symbol
•The 1st letter is capitalized; the 2nd is not
•Ex. Au - Gold

Ag - Silver

Zn - Zinc

Periodic Table

Compounds

•Pure substances are not always single
elements
•Pure substances that are made up of more
than one element combined in a fixed ratio
are called compounds
•Ex. CO2, NaCl, BaCl, H2, H2O, etc.

Salt - NaCl

Carbon dioxide - CO2
Water – H2O
