## Homework Statement

hi, I have this problem that sounds easy (at least I hope so) the question is prove that the entropy goes to zero as the temperature goes to zero

## Homework Equations

segma= -(omega+meo*average{N} -U}/kT

segma=the entropy

omega=grand canonical ensemble partition function

meo=the chemical potential

U=the internal energy

k=boltzman constant

T=the temperature

## The Attempt at a Solution

I usually use this information (segma=>0 when T=>0) to answer other problems, but here I have to prove it. I thought of taking the limit of segma forT=>0, and change the variabels on the RHS as a function of T, then solve it, but it didn't work, I have 3 more days before I hand it over, and I'm revising for another exam . if any one can give me a hint or know a web site can help (I allready search), please do and I'll be thankfull.
