What is matter?
“All matter has volume, mass, density, boiling point, freezing point,
and other properties. These properties can be described as physical
or chemical properties. Matter can change chemically and
physically.”
LESSON 13.1
Measuring Matter

Matter is anything that has
mass and takes up space.

Mass is measured in grams.

Everything you see is
matter.

Mass is a property of matter
that can be measured.

An object’s mass is the
amount of matter that
makes up that object.
Measuring Matter

Volume is the amount of
space that something takes
up.

The volume of a liquid is
measured in milliliters (mL).

A solid volume is measured
in cubic centimeters (cm3 ).

You can find the volume of
some kinds of solids by
multiplying the length by
the width by the height.
Mass and Weight

Mass and weight are
different.

Mass is a measure of
the amount of matter
in an object.

The mass always stays
the same, you find the
mass by using a
balance.
Mass and Weight

Weight is a measure
of the pull of gravity
on an object.

Weight can change
depending on the pull
of gravity.

Weight is measured in
units called newtons.
Density
 Density
is a measure of
the amount of matter
in a given space.
 Volume
is anything that
takes up space and
Density is how much
matter something has.
 Density
=
mass / volume
Volume is anything that takes up space and
Density is how much matter something has.
Using Density to Identify
Substances

You can use density
to identify an
unknown substance.

Every substance has a
particular density.

Usually density differs
from particular
substances.
Physical Properties of
Matter

Physical properties of matter are
those that can be seen or
measured without changing the
substance into something else.
Physical properties include

Whether a substance can dissolve
in a substance

Whether it is magnetic

The temperature at which the
substance freezes and boils
Chemical Properties

A substance’s chemical
properties tell how the
substance forms new
substances when it reacts
with
Examples:

Wood in the fireplace
burning. As the wood
burns, it will change into
new substances.
