I Ideal Gas Law and Differentiation

  1. Dec 17, 2016 #1
    Is it possible to calculate the rate of change of n with respect to rate of change of Pressure and rate of change of Temperature with V unknown but constant by PV = nRT?

    Rate of change of Pressure and rate of change of temperature can be measured. R and V are constants.

    Are you assuming that ##n## varies in time and is not constant ?

    It seems to be possible with simple differentiation. However 'n' must be known at the point of time.

    $$\frac{d\ln{n}}{dt}=\frac{d\ln{P}}{dt}-\frac{d\ln{T}}{dt}$$
