A sphere of aluminium of 0.047 kg placed for sufficient time in a vessel containing boiling water, so that 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 heat capacity of aluminium.
