1. States of Matter

2. There are three phases of matter on
Earth
: Little space
between molecules
and can only vibrate
Have a definite SHAPE
Have a definite VOLUME

3. 2)
: Molecules are
loosely bonded (can
flow past each other)
definite
(can
take the shape of the
container)
a definite
(liquid levels off)

4. 3)
: Lots of space
between molecules
(particles move freely
and collide often)
definite
definite
(molecules spread to all
areas of the container)

7. • Both
and
can
affect the phase of
matter.
• Lower temperature
means less movement
equals solid

8. • Increased pressure on a
gas can force gas into a
liquid.

9. Change in
• During a change of
state, particles in a
substance
OR they
begin to move

10. Change of State
Solid -> Liquid
Melting (add heat)
Liquid -> Solid
Freezing, Crystallization, Congealing (remove heat)
Liquid -> Gas
Evaporation (add heat)
Gas -> Liquid
Condensation (remove heat)
Solid -> Gas
Sublimation (no liquid phase) (add heat)
Gas -> Solid
Resublimation (no liquid phase) (remove heat)

11. • From a solid or a liquid
to a gas
• Energy must be
absorbed to vaporize a
solid or a liquid
