Thermodynamic Questions

  1. Jan 29, 2009 #1
    1. The problem statement, all variables and given/known data

    I am trying to quantify the 2nd Virial Coefficient depending on the temperature w/o using statistical mechanics b/c we haven't covered it yet.

    2. Relevant equations

    [tex]p=p_{ideal} [1+B_{2}(T) \frac{N}{V}][/tex]

    [tex]p_{ideal}= \frac{N k_{b} T}{V}[/tex]

    3. The attempt at a solution

    Now other than just considering the mutual pair interaction from a Lennard-Jones like potential.

    I have noticed that

    [tex]B_{2}(T) \frac{N}{V}[/tex]

    is dimensionless quantity, since [tex]p_{ideal}[/tex] is already in units of pressure.

    Yet, I don't know if is there a physical a meaning of the coefficient from the implied units of [volume/number of particles]. I have looked in a few of my books. I found nothing spelled out.

    Any suggestions? Do I just have to consider this interaction to make my analysis of [tex]B_{2}(T)[/tex]
