Matter

Hello.
Pay
attention
. It does
MATTER!
Gases are formed
when a liquid
evaporates. The
particles in a gas
have enough
energy to spread
very far apart.
When this happens,
it is called diffusion.
Gas is the
most common
form of
matter. Gas
takes up any
space that is
not filled with
a solid or a
liquid.
Solids are formed
when a liquid is
cooled. The liquid
hardens and forms
a solid.
Solids are formed when a
liquid is cooled. The liquid
hardens and forms a solid.
Are you
paying
attention?!
Solids are the least
common form of matter.
Solids are changed
by heat. When a
solid is heated, the
particles gain
energy, allowing
them to spread out.
When a solid
changes into a gas
without turning into
a liquid, it is called
sublimation.
•
When the atoms
mix, they link
together and form
a product. During a
chemical reaction
energy is not
absorbed or given
off. Chemical
reactions need a
certain amount of
energy to set them
off.
Chemical reactions
happen when the atoms
in one substance break
away from each other and
mix with the atoms of
another substance.
THE END
Me too!!
I hope you
enjoyed
the show!!
Goodbye!
