    Is Entropy Extensive in an Ideal Solid?

    I have it setup like this: S(λ E,λ N)=λ S(E,N) c(λN)+3(λN)k[1+ln\frac{λE}{3(λN)h\nu}]=λ{c(N)+3Nk[1+ln\frac{E}{3Nh\nu}] But 1. I don't know how to reduce the left side, and 2. when I distribute λ through the right side, is it on everything ending up looking like this...

    Is Entropy Extensive in an Ideal Solid?

    \frac{}{}Homework Statement Starting from S(E,N)=c(N)+3Nk[1+LN(\frac{E}{3Nh\nu})], derive a version of the Entropy, S(E,N) of an ideal solid that is extensive, that is, for which S(\lambdaE,\lambdaN)=\lambdaS(E,N) Homework Equations The Attempt at a Solution Basically have to...

    Blackbody Radiation Test Question

    Homework Statement The blackbody radiation equations of state are E/V=aT^(4) and P=(1/3)(E/V). From the fundamental state derive a quantity involving only P and V that remains constant when this radiation undergoes a reversible adiabatic transformation. Homework Equations Maybe...
