Thermal conductivity

  1. Jul 24, 2008 #1
    Hi could anyone advise me to weather I am right in thinking when using equation one to calculate the thermal conductivity that Cv is the molar heat capacity and is calculated by use of eqation two for an ideal gas such as argon?

    k=n*<v>*mfp*cv / 3*NA

    Cv,m = (3/2) * R

    Any hints would be much appreciated as the using the above equations i am getting a result which is about 30% out for the expected value of 1.71e-2 J/W/K for the thermal conductivity of argon at s.t.p

    Thanks again in advance

    gem :confused:
