Chemistry is the study of energy and matter.
Everything you touch or see, smell or taste is made up of matter.
Mass is the amount of matter in an object. Mass is often measured in
grams. Mass is the weight of something. The more mass
something has, the more it weighs.
Volume is defined as the amount of space a thing
fills. Volume can be measured in many ways. Some ways to
measure volume are gallons, quarts and pints. A car weighs more than
a skateboard because a car has a greater mass than a skateboard.
Since it takes up more room than the mouse, it also has a greater volume.
Empty space, a place that contains no matter is called a
vacuum.
The density of an object is the measure of how much
matter is in the space that the object fills. Some things don't
contain much matter compared to the amount of space they take up. Take for
example a beach ball and a brick. A beach ball has more volume
(takes up more space) than a brick, but it is much lighter. The
brick is much heavier than the air in the beach ball, but it is
smaller. The brick has a greater density than the air in the beach
ball.

Which of the following statements is true?
A place
that contains matter is called a vacuum.
A place that contains no matter is called a
vacuum.
The
of an object is the measure of how much
matter is in the space that the object fills.
