¥Ideal
Gas Law describes relation between 3 variables: temperature, density and pressure
¥ P(mb) = constant « r(kg/m3) « T(K)
¥ P(mb) = 2.87 « r(kg/m3) « T(K)
¥If you
change one variable, the other two will change.
It is easiest to understand the concept if one variable is
held constant while varying the other two
