Three States of matter
By Brennon BHM
A solid’s shape and volume stay the same
Solid- the state of matter that has a definite shape and
Particles are very close together they have a strong attraction
for each other
Solid all together (slow moving) liquids little pieces moving
together gas all over moving (fast moving)
2 type of solids
Crystalline: Orderly, Particles in a repeating pattern of rows,
particles don’t move around
Ex: iron, diamond, ice.
Amorphous: Particles have no special arrangement,
Particles don’t move around.
Ex: Glass, rubber, and wax.
Liquid –the state of matter that has a definite volume but
takes the same shape of its container.
Particles move fast enough to overcome the attraction
between some of the particles.
Particles slide past each other.
Liquids easily change shape
Liquids do not easily change volume.
Ex: if I had a glass of milk how can you change the shape of
the milk? How can you change the milk’s volume?
All liquids have surface tension.
Surface Tension- a force that holds together particles at the
surface of a liquid.
Surface tension(ST) causes some liquids to form spherical
drops (like water)
Water has a high surface tension
Rubbing alcohol has a low surface tension.
All liquids have viscosity.
Viscosity- a liquid’s resistance to flow.
The stronger the attractions between particles the higher the
One small tank of helium can fill almost 700 balloons.
How is this possible? Air in the tank is under pressure when
in the balloon it isn’t under pressure.
Gas – the state of matter that has no definite shape or
Particles in a gas move quickly, so they can break away from
their attraction for other particles
The amount of empty space between gas particles can
Particles of gas in a helium tank are close together than
particles in a helium balloon.
Air is matter because it can be moved
Ex: the teacher gave us balloons and we turned a table on its
back with the balloons under it and we blew it up, it lifted the
table and the teacher up.
Boyle’s Law- at he pressure of a gas increases the volume
decreases by the same amount.
a diver blows a bubble 10m below water what will happen to
the bubble’s volume as it rises? It gets bigger because it has
less pressure at the top.
When you put a marshmallow in an air vacuum the
marshmallow gets bigger because the pressure decreases
This is the video for the marshmallow man.
A. Energy and changes of state
Change of state- The change of a substances from one
physical form to another
Physical changes (substance doesn’t change)
You must add or remove energy to change the state of a
