I created this presentation for my 10th grade MYP science class's unit on energy and change in chemistry. It's just an introduction to the relationships described by gas law formulas but does not go into detail about how to solve them.
3. Gasof the
4 postulates
Kinetic Theory of
Gases:
4 factors which
dictate how
gases behave:
1.temperature
(T)
2.pressure (P)
3.volume (V)
4.amount (n)
How do each of these factors impact
gases?

kinetic energy
(KE) of all
particles; HOT: COLD:
measured in high KE = fast low KE = slow
Kelvins (K) movement movement

9. Gas of these factors impact
How do each
gases?
2.pressure
(P)
measured
in Pascals
(Pa) or kPa
10. Gas of these factors impact
How do each
gases?
Force is related to KE!
more KE = more force =
if A more P
then P less KE = less force = less
P
2.pressure Since KE is related to
(P) temperature…
measured
in Pascals WHAT does that mean
(Pa) or kPa about force and
temperature?
if F
then P

V
smaller volume = less space
larger volume = more space P
3.volume (V) = more collisions = more
less space
pressure
more space = fewer collisions = less
pressure
