Homework Help: Dielectrics, heat capacity and polarization

  1. Dec 13, 2013 #1
    Consider a dielecrtic with polarization P=(a+b/T)[itex]\epsilon[/itex] and heat capactiy C[itex]\epsilon[/itex]=A+B[itex]\epsilon[/itex], where a and b are constants. Show that B=2bV/T2 and find the isothermal dielectric constant [itex]\kappa[/itex]el. Use properties of G(T,[itex]\epsilon[/itex])

    I'm really not sure where to start with this one. Any help is apreciated to get going in the right direction.
    I know εVel/a
    The only think I found in my notes is that C[itex]\epsilon[/itex]=-T(∂2G/∂T2)ε but I'm not sure how that plays into the question..
