CHAPTER 3 STATES OF MATTER





SOLIDS- definite _____________and volume
LIQUIDS- definite __________but no definite________. Takes the
shape of the _________
GASSES- takes the _______and volume of the _________r----ex
balloon depends on whether the volumes and shapes are definite
or variable
Plasma
Bose Einstein condensate
Kinetic Theory
 mid 1800’s—all particles of matter are in _________motion
 Kinetic energy is energy of _______


Behavior of gasses




Kinetic Theory applied to gas has 3 points




Particles moving _______and colliding with each other. The
collisions result in ___________energy being produced.
These collisions will take place only __________the container
where they are located
Ex. Air in a tire
Particles in a gas are in __________random motion
The motion of one particle is unaffected by the _________of other particles
unless the _____________collide
Forces of attraction among particles in a ______can be ignored under
ordinary ____________
Behavior of Liquids

Particles more ____________packed than a ________

Attraction of particles affect ____________

A liquid ____________________________of its container because the
particles can _________to a new location

BEHAVIOR OF SOLIDS
Solids have a ___________volume and
__________because particles in a solid __________around
fixed locations

PRESSURE
The result of _______distributed over an area
FORCE
Measured in ________( N)
Area is measured in square meters
______________between particles of a _______and the walls of
the container cause the PRESSURE in a closed container of gas
The more frequent the collisions the _________the pressure the
gas has
_________and _____affect pressure
FACTORS THAT AFFECT PRESSURE
Temperature- _______the temperature the _________the
pressure. If the volume and number of particles is constant
The temperature ______makes the particles _____________in
collisions and move faster
They hit the walls with _______force ex. Tire pressure
VOLUME
As volume ___________particles of trapped air collide more often
with the walls of the container
____________the volume of gas, ____________pressure if the
temp and the number of particles are constant

Ex. Lungs (inhale) increase volume up ________down (exhale)
volume down pressure ____
NUMBER OF PARTICLES
 _________in the number of particles increases pressure of
a gas if temperature and _________are constant
 Ex. Balloon bursting

Sublimation
Deposition
Change from one state of matter to another
The ____________of a substance does not change during
a phase change
 ENERGY AND PHASE CHANGES
 Energy is either ____________or ___________during a
phase change.
 Usually in the form of _____energy
 Ice forms>energy _________
 Ice melts> energy _________
 Melting - absorb
 Freezing - release
 Vaporization – absorb
 Condensation- release
 Evaporation-absorb
 Endothermic>absorb heat
 Exothermic>release heat

BOILING----- molecules move _________and faster and
_________away from each other
 Condensation---gas or vapor to liquid
 Sublimation—endothermic directly from a ________to a
gas w/o changing into a _______
 Deposition---exothermic gas or vapor into a solid ex.
