PROPERTIES AND

Matter
MATTER IS EVERYWHERE AND
EVERYTHING!
MATTER IS ANYTHING THAT TAKES UP
SPACE!
MATTER IS MADE UP OF TINY PARTICLES
CALLED ATOMS!
Matter
Matter can be found in three different types.
These three types are considered the three
STATES of MATTER.
- Solids
- Liquids
- Gasses
States of Matter
SOLIDS
A SOLID is a matter that has a defined shape and
will not lose its shape.
FIXED VOLUME AND FIXED SHAPE
Examples of solids:
- Chair
- Table
- Golf Ball
- Hockey Puck
- Glass Jar
States of Matter
GASSES
A GAS is a matter that does NOT have a fixed
shape or volume but will completely take up all
the space in a container.
MOST GASSES ARE INVISIBLE!!!!
Examples of GASSES:
- Oxygen
- Helium
- Carbon Dioxide
- Nitrogen
- Carbon Monoxide
PROPERTIES OF MATTER
CHEMICAL PROPERTIES
- Chemical properties
can be measured only
by changing a
substance’s chemical
identity.
PHYSICAL PROPERTIES
- Physical properties can
be measured without
changing a substance's
chemical identity.
Changes in Matter
Matter can go through two different types of
changes.
Types of Changes:
- Physical
- Chemical
Physical Changes in Matter
A physical change in matter is when
matter changes its property but not its
chemical nature.
Physical Changes in Matter
Examples:
- Shape
- Texture
- Size
- Dissolves
- Breaks Apart
Physical Changes in Matter
EXAMPLES:
Aluminum foil is cut in half
Clay is molded into a new shape
Butter melts on warm toast
Water evaporates from the surface of the ocean
Juice freezes
Rubbing alcohol evaporates on your hand
Chemical Changes in Matter
Chemical change:
The substances present at the
beginning of the change are not
present at the end; new substances
are formed. The change cannot be
“undone."
Chemical Changes in Matter
CHEMICAL CHANGES
THE MATTER IS
DIFFERENT.
THE PARTICALES OF THE
SUBSTANCES ARE
BROKEN APART
THE OLD MATTER IS NO
LONGER PRESENT
ATOMS ARE
REARRANGED INTO NEW
PARTICLES
THE ORIGINAL MATTER
CANNOT BE REMOVED
FROM THE NEW MATTER
A NEW SUBSTANCE IS
FORMED
MATTER: WHAT’S
ITS WEIGHT?
WEIGHT
Every object can be described based
on its weight. The heavier an object is
the more it weighs.
