146641 Two identical system, with heat capacity at constant volume that varies as Cv=b3 (where b is a constant) are thermally isolated. Initially, one system is at a temperature 100 K and the other is at 200 K. The system are then brought to thermal contact and the combined system is allowed to reach thermal equilibrium. The final temperature (in K ) of the combined system will be
