Ideal Gas Law
Q: How can
pressure change?
Air can
approximately be regarded as an "ideal gas"
ideal gases obey
the "ideal gas law":
P = CrT
P
= pressure exerted by the gas
C
= constant
r = density of the gas =
mass/volume
T
= Temperature of the gas

- Q: So, from the ideal gas law,
what can affect the pressure of a gas?
