TYPES OF MATTER Flashcards
Is anything that has mass and takes up space
Matter
Three states of matter
Solid, Liquid, Gas
-Molecules tightly packed
together and don’t move around
much.
-Particles in a solid have strong
bonds between each other.
have a fixed volume and
shape.
-The molecules in a solid can
vibrate but the structure doesn’t
not change.
Solid
-Molecules more spread out and
can move around and bump into
each other.
-Bonds between particles are
weak.
- have a fixed volume but
can change shape. They take the
shape of the container they are
in.
Liquid
-Molecules are far apart can
move around freely and quickly.
-Bonds between particles are
very weak.
-The shape and volume of a ___
are not fixed.
Gas
Changing states of matter
Physical Change
Chemical Change
-Change from a solid
to a liquid
-The melting point of
a substance fixed in
pure substances
Melting
-Change from liquid to
gas
-The temperature at
which when a liquid
freezes is called the
freezing point
Evaporation
A change from solid to gas without its becoming liquid
Sublimation
When a substance in
gas form a changes
states to become a
solid
Deposition
-Change from gas to
liquid
-The particles lose
energy and move closer
together as the gas
cools therefore
increasing the attraction
between them
Condensation
A change where a new form of matter
is made
Chemical Change
-will change the visible appearance,
without changing the composition of
the material
-Can be irreversible or reversible
Physical Change
Sign of chemical changes:
Gas production
Precipitate formation
Energy production
Change in temperature
Change in color
Change in chemical or physical property
Depends on the amount of matter in a
sample
Extensive property
