Matter
Matter is anything that has
mass and takes up space.
Everything has Matter or is
Matter. You are Matter. Books
are Matter. Even a
marshmallow is Matter.
There are 3 states of Matter.
Solid , liquid, and gas.
Change of State
A physical change that occurs
when matter changes from
one state to another, such as
from a liquid to a gas.
Physical Changes
A change in which the
form of a substance
changes but the
substance still has the
same chemical makeup.
Chemical Changes
A reaction or change in a
substance, produced by
chemical means, that results
in a different substance.
Law of Conservation of Mass
The total mass of the
products that form in a
chemical reaction is equal
to the total mass of the
substances that react: No
matter how many pieces an
apple is cut into, the law of
conservation of mass says
that the mass is conserved.
