"The entropy of a two-dimensional gas of N particles in an area A of energy U is given by:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]S=Nk[ln \frac{A}{N} + ln \frac{mU]{2 \pi \hbar^2 N} +2][/tex]

Calculate the temperature of tge gas and the chemical potential."

I have absolutely no idea how to even begin. There was some bit of some previous lectures that used the clausius entropy principle to derive some partial differentials expressing different parameters in terms of entropy, but other than that, I'm lost. The two-dimensional bit is even more confusing. I gather that this affects the number of degrees of freedom, but how one goes about modifying the theory to aco**** for this, I have no clue.

edit: gah. I have no idea how the tex formatting screwed up. I've done it, as far as I can see, exactly how the help topic says.
