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.

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?

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

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

It is Expressed
also as
Boyle’s P1V1 = P2V2

26. Gas
V1/T1 = V2/

27. Gas
