Example: Ideal Gas
Law
If Pressure at Sea Level averages 1013 mb
and Temperature at
Sea Level averages 288 K, what is the
average Density at Sea Level?
Answer can be found using the Ideal Gas Law
P(mb) = 2.87 «
r(kg/m3) « T(K) r(kg/m3) = P(mb) / {2.87 «
T(K)}r(kg/m3) = (1013 mb) / (2.87 «
288 K)r(kg/m3) = 1.23 kg/m3 È 2.00 lbs/yard3
