Two thermally isolated identical systems have heat capacities which vary as C = BT (where B 0). Initially one system is at 300K and the other at 400K. The systems are then brought into thermal contact and the combined system is allowed to reach thermal equilibrium. The final temperature of the combined system is... [UT-JAM 20131
