How does the transition temperature T_C depend on the number of particles N if E=pc for Bose condensation? (Hint:You don't have to evaluate any integrals. Just try scaling, i.e., make the variables in the integral dimensionless. Your answer should be of the form $T_C\sim N^{\alpha}$. Find $\alpha$.)
