Properties of the 3 States of Matter
Review how particles are arranged, how particles move. How they are changed by
temperature. Put an “X” in the box if the description applies to it or answer what the
Properties are asking.

Anything that has mass and
takes up space
the amount of matter
making up an object
how much space an object
takes up
The mass of the matter in the
given space
The upward for of a liquid or
gas on an object
The state of matter that has a
definite shape, mass and
volume. Particles are packed
tightly together
The state of matter that does
not have a definite shape but
does have a definite volume
and mass. The particles are
less tightly packed.
The state of matter that does
not have a definite shaper or
volume. The particles move
around freely.
A change in state of matter, size, shape
or form.
A change in matter when the
substances that make up an object have
been changed into another substance,
usually with the help of a chemical
reaction or heat/fire.
Measures the amount of gravity
between an object and a planet.
