A sphere of aluminum of 0.047kg placed for sufficient time in a vessel containing boiling water, so that the sphere is at 100°C. It is then immediately transferred to 0.14 kg copper calorimeter containing 0.25 Kg of water at 20°C. The temperature of water rises and attains a steady state at 23°C. Calculate the specific capacity of aluminum.
