The Properties of Matter
Section 1: What is Matter?
• Matter – anything that has mass and takes
– Examples: air, water, books, hair, pencil, etc.
• Volume – the amount of space an object
takes up; all matter has volume
– Different objects cannot occupy the same
space at the same time.
• The volume of a liquid is measured in
Liters (L). Small volumes are measured in
milliliters (mL). Large volumes are
measured in kiloliters (kL).
• Liquid volume is measured using a
graduated cylinder (graduate).
• Measure liquid volume at the bottom of
the meniscus (curved surface of the liquid).
• The volume of solid objects is measured in
cubic centimeters (cm3).
• The volume of a regularly shaped object is
measured using a metric ruler.
• The volume of regularly shaped solid
objects is found by multiplying
length x width x height
• Some objects, like rocks, are irregularly shaped,
so you cannot find volume by multiplying length
x width x height.
• Instead, use the water displacement method.
Place a measured amount of water into a
graduate. Place the solid object into the water.
Notice that the water level rises. Find the
difference in the water level. This is the volume
of the object.

• Mass – the amount of matter in an object
• The more matter in an object, the more mass the
• Mass is measured in grams (g). Small masses
are measured in milligrams (mg). Large masses
are measured in kilograms (kg).
• Mass is measured using a triple beam balance.
• Weight – the measure of the pull of gravity
on an object
– Gravity is a force of attraction between two
• Weight is a force, so it is measured in
• Weight is measured using a spring scale.

though you weigh less.
• Inertia – the tendency of an object to resist a
change in motion.
• If an object is in motion it will resist stopping. If
an object is stopped, it will resist moving. Inertia
is NOT a force.
• The more mass an object has the greater its
