A copper ball of mass 100 g is at a temperature T. It is dropped in a copper calorimeter of mass 100 g, filled with 170 g of water at room temperature. Subsequently, the temperature of the system is found to be 75°C. T is 30°C, specific heat of copper (Given, room temperature = = 0.1 cal/g °C) (a) 885°C (d) 800°C (b) 1250°C (c) 825°C
