KINETIC MOLECULAR THEORY
 All matter is made up of particles (atoms and molecules) that are in a state of
 These particles are in motion, because of a combination of
.
 An increase in motion of the particles in a substance make it feel
, and a decrease in
motion make it feel
SOLID


hold
particles in a solid together
Particles _____________ because
of their kinetic energy and are
limited in their movement
LIQUID


Particles have more kinetic energy
than solids and weaker
___________________________
Particles vibrate more rapidly and
___________________________
(causes liquids to flow)
GAS


Particles have more kinetic energy
than liquids of solids and _______
___________________________
Particles move more rapidly and
___________________________
THERMAL ENERGY
 Thermal Energy is the



 in speed of particles 
 number of particles 
Objects that absorb thermal energy have
_____
particle movement which causes the object to _________
. Objects that release thermal energy have
particle movement which causes them
to
.
Thermal energy can only be transferred from _________
to

HEAT
TEMPERATURE AND THERMOMETERS
 Temperature is
(The more kinetic energy particles have, the faster they move, and the higher the temperature)




A Thermometer is a device used to
. It is made of
narrow sealed glass tubes containing
or
As the temperature of the substance increases, the particles of the substance
move
and bump into the glass of the thermometer and make it
vibrate more
The faster moving particles of the glass tube now
with the slower
moving particles of the mercury or alcohol making these particles
.
The faster moving particles of the mercury or alcohol

Temperature Conversion Equations:
𝑇𝐶 = 𝑇𝐾 − 273


𝑇𝐾 = 𝑇𝐶 + 273
The SI Unit for Temperature is the
The size of one Kelvin is equal to the size of one degree Celsius
THERMAL ENERGY, TEMPERATURE AND PHYSICAL STATE
 Substances increase in temperature when they
(warm up). The
temperature at which a solid changes to a liquid is its
. The temperature at
which a liquid changes to a gas is its
.
 Substances decrease in temperature when they
(cool down). The
temperature at which a liquid changes to a solid is its
(equal to the
melting point). The temperature at which a gas changes to a liquid is its
. (equal to the boiling point)
