A platinum ball of mass 100 g is removed from a furnace and immersed in a copper vessel of mass 100 g containing water of mass 390 g at 30°C. The temperature of water rises to 40°C. Calculate the temperature of the furnace. (Given that the specific heat of platinum = 168 J kgK, specific heat capacity of copper = 420 J kg1 K-' and specific heat capacity of water = 4200 J kg¯' K). %3D
