(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using the viral theorem, the heat capacity of a star is given as C=-3*k/2.

Using this, I need to calculate the entropy of a star in terms of the average temperature T, then in terms of U (total energy).

2. Relevant equations

dS=C*dT/T

3. The attempt at a solution

To solve for S, I integrated getting S=-(3/2)*k*ln(tf/ti)+C. How do I solve this for S? This function is undefined when Temperature is 0...

Thanks in advance!
