146641 Two identical system, with heat capacity at constant volume that varies as $C_{v}=b^{3}$ (where $b$ is a constant) are thermally isolated. Initially, one system is at a temperature $100 \mathrm{~K}$ and the other is at $200 \mathrm{~K}$. The system are then brought to thermal contact and the combined system is allowed to reach thermal equilibrium. The final temperature (in $\mathrm{K}$ ) of the combined system will be
